Not sure if this will help, but find my device on F-Droid is awesome. You can use generic SMS and send “fmd locate” or you can use third party apps such as signal. This makes it so it’ll only trigger whenever you receive that text message rather it running 24/7

It allows you to setup a trusted set of contacts who can then send you a text message “fmd locate”, and it’ll reply with an openstreetmaps link showing where you are. It’s not real time tho

And you can disable it simply by turning off your location
