NYT is reporting that Pakistan is saying the Ayatollah agreed, and it was due to Chinese pressure regarding the global economy.

It seems to be more likely on the unlikely side because (1) Iran planned for distributed operations (2) missiles are still apparently flying, speculated that any agreement may not have disbursed to all the independently operating groups (3) your point, it's unclear if there is any actual agreement (4) is Israel party to this agreement, will they honor any such agreement? Same for Hezbollah and Hamas

Probably not since they just launched a barrage of ballistic missiles.
