How to have the same repo shown on multiple github profiles?

I’m in the following situation: I’ve created a repository with my private account. I’m also part of a laboratory. My lab has a separate github account. I want to “share” my github repo with my lab’s account so that if someone clicks on my lab’s github profile they’d see the repository.

Something I tried: added my laboratory’s account to my repo as a collaborator. The repo wouldn’t show up on my lab’s account.

Question: Can someone advise on what the best way would be to accomplish this? Thank you.

Edit: the repo in question is public.
