Are you wanting to be added to the trusted list of these profiles or add non-Wiki-tree members to your WikiTree profiles? If the former you need to have the PM of the profile add you to the trusted list. If the latter, you need to have a profile (and thus an ID for the person you want to add to the trusted lists of people you're the PM for. Actually I've never used the bulk add, but as I understand it, you can only bulk add ancestors and descendants of the profile you're adding someone to the trusted list of. (sorry any grammar police in the vicinity, but I couldn't figure out a way to say it correctly without the "of" at the end of the sentence)
