Can't find new users that was just added

I can’t seem to find the user that I just added to the platform. I sent an email to him and now I can’t seem to add him to the table.

Does the user have to click accept or something before they show up in this list?

Never mind! I can see that I actually had to add them to the table beforehand. So the new user already had access to what they needed to but for some reason I thought they didn’t because they didn’t show up in the list.

So I guess maybe they should change to a suggestion that we show that the user already has access or show the users who do have access on this page?
