Calendar invite to team when scheduling channel meeting - not possible despite new teams feature?

Hi Christian, thank you, I did read this one - but it's from October 2020 and I thought something might have changed since then?

Our problem might go further than this article goes as well:
In the article, the team name appears under meeting attendees (See figure 1). For us, this does not happen, unless we a) manually put the Microsoft365 group on the Global Address List in the admin console, or b) create a Microsoft365 group first and THEN create a team.
If we go route b), then this also enables calendar invites to be sent out to everyone in this group once we enter the group name when we schedule a meeting on teams. However, this is obviously not an option for existing teams.

The article you link here suggests that for Teams created on Teams, members are not added to the subscriber list. I understand this could be the problem (which might still persist now, about 5 months later). However, I had the (possibly silly) hope that there is another problem in the communcation with Microsoft365 for us, as a created team does not appear under attendees unless manually put on the Global Address List. The (again, possibly silly) hope is that if we fix that, everything else will work as it should and send out calendar invites if a team/group is added to the attendees.

Does this train of thought make sense to you?
Would the code in your suggested article even work if there might be something different in the settings anyway, as teams we create do not appear as meeting attendees/are not on the GAL? No one in our organisation is particularly experienced with coding that goes beyond simple HTML so we are a little worried.

There are differences if you have an exchange hybrid environment also. In that case a newly created team will act as following. Members with EXO will not receive invitations to a channel meeting unless explicitly invited. But all on-prem users will get the invite.

I would like to see a more controllable solution where the person that creates the meeting can chose which behavior the invite should have. I.e send invite to all team members/send invite to only chosen participants.

There are use cases for both behaviors. Some times I want to have the meeting within a channel in a big team but only need some to participate but obviously if any one in the team notices that the meeting is ongoing, the can join in. But more to the point I want the artifacts from the meeting to stay within the team itself.
