Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Dmitry,
Thanks for posting here.
In Teams > Planner tab, the first time you need to create the Checklist in that new task detailed page manually. And then Assign this task to users.
The next time, you can copy the first task to a new one and then assign this new task to users.
Hope the above information helpful.
Regards,
Rudy
