Types of rapid tests available?

Hi. Planning on coming to Zihua in February from the U.S. From what I can tell, rapid tests are accepted before traveling back to U.S. There’s mention of even bringing your own, making sure the brand is acceptable, but I can’t find any details. (Wondering if it’s worth it to bring a rapid test with me.) If I’m staying at a small local place right on LaRopa beach, what’s the easiest way to get tested the day before departing back to the U.S.?
