I think I found how to do this, or at least the only workaround I could figure out since the hovering option did not work for me.
Select the use in the Admin Center to open more options. Then under 'Microsoft 365 activations', select the link for "View Microsoft 365 activations." The next window that opens will have a button at the bottom to "Send Invitation Email."
This opens an email message with a link that you can send to the new user.
