For a summary of the current situation with the HA Life360 integration and suggestions for getting it working, see this post.
FWIW, you should not need to use any “workaround” or my “ha-life360” custom integration. The standard, built-in life360 integration should work now, assuming you do not verify your phone number with Life360, or if you have, if you “un-verify” it. Again, see details in the linked post.
