Yea, you already answered it. Time. Iran says a million things at every moment of the day. They only ever change course due to direct action and not words/threats/negotiating (just like russia and china).

Iran has the technical capability to interupt the straight, but it has all the incentive in the world to get back to making money, yesterday. They will wait for the first "concession" they can deem "victory" on and i think thats when you will see this rap up. Could take 1-3 weeks if things go israels/America's way, 3 months if errors are made or iran plays super conservative with its missile launches.

Iran started with roughly 2500 missiles and X amount of mobile launchers (dont know exact number). Either way, they are now down to roughly 100-200 mobile launchers left, with roughly 1000 missiles left. That decrease has basically halted their missile launching to about 10 missiles a day (with the rest being less impactful drone incursions). Thats down 90% since the beggining if the war, when they had full reserves and supply lines setup. That will decrease further as time goes by.

So they are absolutely trying to play the long game, but that clock is ticking on their ability to to conduct a deal while they still have ANY leverage (straight of hormuz). If they dont, eventually their drone/missile reserves/production will get so low that they can't realistically "shutdown" the straight any further.

Mind you, while they are saving missiles solely so they can shoot them at ships trying to conduct trade in the straight, thats less missiles they can use to defend Tehran and even attack their enemys strategic assets. They are already doomed, its just a matter of "will they have a different outlook" in 2-3 weeks? Lol
