Best Practices for Executive Assistants/Delegates when booking virtual events

Greetings folks:

I wondered if there are some of you who have some best practices you've adopted/used as executive/virtual assistants when you book large meetings (i.e. Townhalls/All Hands) sessions as it seems that delegate access to booking items out of some else's calendar in Outlook using Teams adds a layer of complexity that I have not quite finessed so that the experience/process is user friendly.

Please advise if you have any ideas to share; it would be appreciated.

Cheers!
