It’s right there in the article.

According to Channel 12 reporter Yaron Avraham, on October 16 and 17, “the [Security] Cabinet deliberated for hours over the precise wording of the decision, with each draft being passed between the Cabinet room and Blinken’s room, a distance of a few meters away, inside the Kirya…. Eventually, around 3 a.m., they arrive at an agreed upon text that is read in the Cabinet room in English.”

Avraham’s account of the process was independently corroborated by a reporter for the competing Channel 13, who wrote: “The discussion with Blinken is conducted as follows: he is sitting in a room in the Kirya with his advisors and security team, while Security Cabinet holds the discussion; [Minister of Strategic Affairs Ron] Dermer goes back and forth and interfaces with him.”

Blinken, for his part, concluded the day with a triumphant speech taking responsibility for the restarting of humanitarian aid to Gaza:

"To that end, today, and at our request, the United States and Israel have agreed to develop a plan that will enable humanitarian aid from donor nations and multilateral organizations to reach civilians in Gaza – and them alone – including the possibility of creating areas to help keep civilians our of harm’s way. It is critical that aid begin flowing into Gaza as soon as possible.

We share Israel’s concern that Hamas may seize or destroy aid entering Gaza or otherwise preventing it from reaching the people who need it. If Hamas in any way blocks humanitarian assistance from reaching civilians, including by seizing the aid itself, we’ll be the first to condemn it and we will work to prevent it from happening again."

Then later on it says:

In a Zoom call with party members, Sa’ar declared “I’m currently of the opinion that humanitarian aid to Gaza should be halted immediately, until the formulation of a humanitarian aid [mechanism] which will not be subject to Hamas takeovers, nor the distribution of aid by Hamas to the civilian population.”

This policy, Sa’ar said, was already anchored in “a [Security] Cabinet decision that was made at the beginning of the war, which stated that the humanitarian supply from Egypt will be allowed as long as this supply did not reach Hamas, and that the supply that does reach Hamas will be thwarted.” According to him, the policy was endorsed by “The United States of America … in the talks that took place in the middle of October, including the talks with Secretary of State Blinken, who was visiting [Israel] and took part in discussions, mainly with the War Cabinet, on the subject of humanitarian aid.”

Further on regarding the WCK strike:

The Israeli military ended up putting the blame on Colonel Nochi Mendel, who ordered the strike, and has previously expressed support for halting aid provision to Gaza. Mendel’s punishment amounted to being let go from his military service, and going back to his prestigious day job as director of the Settlement Department at the Israeli Ministry of Defense.

But the right wing Makor Rishon newspaper concluded, on the basis of conversations with drone operators involved in the assassination of the aid workers, that Mendel was only implementing the official policy jointly set by Blinken and the Israeli cabinet back in October: “The mission order made it clear that the IDF is instructed to thwart an attempt by Hamas terrorists to take over the aid trucks that entered Gaza. The IDF received this instruction from the Security Cabinet at the beginning of the war, sometime around October 18, 2023, following heavy pressure from the United States.”
