Admin unable to create new Application Password for user with no role on main site (multisite)

[roytanck]

I ran into this while trying to create an Application Password for a user from the network users admin screen (wp-admin/network/user-edit.php). It does work from any site's dashboard subsite/wp-admin/user-edit.php .

Steps to reproduce:

• I used a completely multisite WP 6.4.2 in subdirectory mode.
• Log in as an administrator.
• Create at least one additional site (I called it "subsite").
• Create a second user, and make them subscriber on "subsite".
• If present, remove the user from the main site.
• Go to the network "Users" screen, and edit the user.
• Try to add an Application Password.

I got an error saying Invalid user ID..

I'm starting to wonder whether it makes sense to create application passwords at the network level at all. In the context of a (sub)site, it's clear that you're allowing access to that site. In the network admin, users could expect they're granting access to all sites, which I don't think is something WP supports?

Perhaps the best option is to remove the UI when editing a user in the network area?
