If you cannot find Beekast in the Teams applications. Your Microsoft Teams subscription does not allow it or your organisation has not yet given you permission to use the Beekast tool on the Teams platform.
Ask the IT to give you permission or to upgrade your Teams subscription.
Yes, in Teams, you will be able to choose one of the sessions in your account for which you are an Owner or Host, but it is not the My Sessions area. Also, you cannot “create” a Beekast session directly in Teams (you can only do so from the My Sessions area).
No, don't panic! The two accounts are separate. Deleting one does not delete the other. However, this is not true for sessions or activities. Deleting a session on one of the two tools will be effective on both tools.
Yes, it is possible to be a session facilitator on Teams. Nothing changes compared to using Beekast as a normal session leader. You will be able to scroll through the slides, create content, moderate participations, etc.
