They won't be seen as tokens, but as characters, which will be visible to anyone who the character is set for "in journals" can see the character in their journal, and anyone on the "can be controlled by" can place them. If you want it to show a preview image in the journal, you can also set the avatar for the same image (note avatar does not create a token, only an image for the journal, even if you set an avatar, you still need to at least once put the token onto a map, and click "use selected token" on the character page. and yeah, Pat and Aaron mentioned the wiki page of the end result of that.
