How are you running 1:1 meetings inside Teams without it turning into a mess?

Right now were using a shared OneNote for agendas and action items but honestly nobody updates it and half the time the meeting turns into a random chat with no structure. I tried using Planner tasks as a workaround but thats clunky because theres no real connection between the task and the meeting itself. Has anyone found a good way to keep 1:1 agendas, notes, and follow ups all in one place inside Teams? We have about 40 people so it needs to scale a bit.
