@jakubvysoky Hi, not sure this will answer your question as I don't really understand it. But when you schedule a channel meeting the organizer is the group (the Team) itself even though the one scheduling has the ability to modify it. If you're looking for an easy way to view scheduled meeting you can add the new channel calendar app by "Add a tab" and "Channel calendar". The meeting is also posted in the channel itself.
For more info about the app and channel meetings.

If you're an admin you can use the audit log to see almost everything.
