Hi @Lukasz_Gornicki welcome to the community!
Per my understanding, authorized project administrators will have access to schedule committee meetings.
You can set these project administrators in ‘Basic’ under your personnel settings.
Right now this is a feature coming soon and would be found in ‘meeting management’
under IT Services.
The process should be automatic and simple, you should not have to provide your own zoom account.
Currently we provide a shared pool zoom account that will be auto-provisioned from a common pool that LFX maintains. Meetings can be scheduled for a duration of up to 10 hours in PCC as mentioned in our PCC FAQ: Project Control Center Committee Meeting Management FAQ - Content & Articles - LFX Community Forums
Can your explain your use case here? Would you need to schedule meetings longer than 10 hours?
