Hi @IBN
We need our guests to be able to access the calendar, book meetings, record meetings, access the meeting comments and attendee lists.
The guest experience has limitations by design. These permission is not available for guest users. the following link shows the permissions for guest users for your reference:

Can these permissions be applied to a certain team and not the whole organization?
What is your meaning of certain Teams? Do you mean channels in Team?
If so, Team owners can set guest permissions for channels. To set guest permissions, you could find the step from this article.
