Power Automate Action to add Team members to a private channel

I would like to write a power automate flow that adds new members (not guests) of a team to all private channels in the team. 

I thought I could do that with Power Automate, but there are no Private Channel actions yet. Will private channel actions be added to power automate later, if yes, about when?

Or is there another good way to do this?

Thanks in advance
