Find-My alternatives

Hello. I just got a google pixel with grapheneos, and would like a way to use Apple’s find-my or something similar with family members who still use Apple. I would like something open source that can either proxy my location to Find My or serve as an alternative. I know these apps and services are inherently not private but I do need it so please don’t be the guy to say “just don’t use it,” I would if it were an option. Thanks.
