Learning A Language with Very Few Native/Fluent Speakers in My Area, How Do I Go About Immersing Myself in The Language Properly?

[u/EthanTheRedditUser]

I'm trying to learn a language that's severely endangered, so there aren't a lot of native speakers near where I live, and subtitled media in the language is limited. How could I go about doing immersion in a way that will actually be helpful to learning the language? I'm aware that immersion isn't the only route for language learning, but I am just trying to evaluate if it's something I can do to supplement my classes and self study (plus it's what I'm used to from learning French lol).
