If I need to add multiple members to a private channel in Microsoft Teams, I have to add each new member individually. It would be good if there is a way to add multiple new channel members at once. Similar to how the option already exists for new team members (see https://learn.microsoft.com/en-us/graph/api/conversationmembers-add?view=graph-rest-1.0).
Especially since currently only 40 members can be added per 10 minutes via Microsoft Graph.
Shared channels allow up to 5000 direct members (https://learn.microsoft.com/en-us/microsoftteams/limits-specifications-teams#limits-for-shared-channels). Adding this via Microsoft Graph would take over 20 hours with today's throttling limits.
