Problems using New-MgTeamChannelMember

[karenk-tara]

I have a script that is generate a Microsoft Team with a private channel. Once this private channel is created, I want to add specific individuals to the channel. Every time I'm executing New-MgTeamChannelMember I'm getting a "Parameter set cannot be resolved using the name parameters" message. I've look at this over and compared to numerous other examples of how this should look and I'm at a loss as to what is wrong. Could someone provide some guidance as to how I can resolve this?

I'm using version 2.28.0
