There’s a few 3rd party solutions that are compatible with Google’s find my device coming out this year. Pebblebee just released a few trackers, and iirc chipolo is working on one too.

That is what the Ad Nauseum extension does: “AdNauseam works to complete the cycle by automating ad clicks universally and blindly on behalf of its users. Built atop uBlock Origin, AdNauseam quietly clicks on every blocked ad, registering a visit on ad networks’ databases. As the collected data gathered shows an omnivorous click-stream, user tracking, targeting and surveillance become futile.”
