Describe the feature

Adding a private channel with Application Permissions by providing a list of members.
We can add private channels if we use delegated permissions, but this does not work on behalf of a user (using Application permissions), because graph requires a members property as seen here Create channel - Microsoft Graph v1.0 | Microsoft Learn

Describe the solution you'd like

Add the option to provide a list of members when adding a private channel. Maybe the TeamChannelOptions can be extended to accept a list of UPN's or Ids?

So we could do something like:

await team.Channels.AddAsync(channelName, new TeamChannelOptions
    { 
        Description = "This is my cool new Channel, check this out!", 
        MembershipType = TeamChannelMembershipType.Private,
        Members = [ "00000000-0000-0000-0000-000000000000", "00000000-0000-0000-0000-111111111111
", "[email protected]" ]
    });

Additional context

I searched the issues and discussion but could not find a similar issue or request. If I missed it, please point me in the direction and feel free to close this. Same if this is already possible and I'm the issue.
I do think this 'feature' is available in PnP-Powershell Add-PnPTeamsChannel | PnP PowerShell.
This feature request specifically mentions private channels, but I think the same applies to shared channels.

Good ask @rollsrobby .

Adding some code pointers for reuse: https://github.com/pnp/pnpcore/blob/dev/src/sdk/PnP.Core/Model/Me/Internal/Chat.cs#L24-L34 and https://github.com/pnp/pnpcore/blob/dev/src/sdk/PnP.Core/Model/Me/Public/IChat.cs#L53

Thank you for the pointers @jansenbe . I will try to work on this and open a PR in the near future if that's ok. I will need to read through the contribution docs before though...
