Add Contacts to a Team Chat private ‘Channel’.

Hi Zoom (or Zoomers),

I have a pro account. I updated the Zoom Client this week.  I am using Windows 11.

I have three external Contacts in Team Chat. 

I have created a Team Chat private ‘Channel’.
I have selected the following option in the channel settings: “External users can only be added by account owner and admins”

I select the Channel ‘Add members’ option.

The ‘Add members’ dialog box shows my three External Contacts.

The dialog box seemingly does not allow me to 'select' any of the three External Contacts.

The ‘Add’ button at the bottom of the dialog box is greyed out.

As a plan B… I sent a link to the channel to an external contact.  When the external contact taps on the link… he is told: ‘The channel cannot be found’. 

Let me know if I can supply any other information.

Thanks in advance for your help !
