Microsoft 365 Power Platform - Adding Guests to multiple groups

Description

We're looking for a solution that uses M365 Power app that:
Allows authenticated internal admin users (a security group) to Invite and add Guests to the tenant.The admin can see a list of Microsoft Teams > Channels to which they can add the Guest to.On Submission the request needs to be approved by a member of a group with mail notification that approval has occured.
Guest User details require:Firstname / LastnameEmail AddressSponsor
Some additonal Information:Teams Channels and security groups already exist.Teams and Channels are Private.In some cases there are multiple security groups that handle acces to a Team and Channel, so the permissions logic might look something like:
Team 1 Channel 1- Channel Specific Security Group Channel 2 - Channel specific security Group + Additional Group(s)
