I’ve been using this which works great.
f-droid.org/packages/com.sbv.linkdroid/
Works with my single sign on setup as well which was critical. Creates a nice share target on android so any share button gives the option of sending the link to linkwarden

You know what, I like it more than LinkGuardian. Great suggestion!
