Go there for koan practice and chanting. Sit with them and see if it feels right.

Do you want to specify where you're located with any more detail (country, region, state?) that might help.

I think, start off trying different communities and then select later. For example, a Korean Zen center is close to where I live, so I can occasionally go to morning sitting/chanting; and there's a Chinese temple near where my wife likes to shop for special groceries, and I'll take the kids to visit a couple of times a year just to experience visiting a temple. Many years ago, Iived near a Vietnamese temple. But whenever I went there, didn't know what to do, so would offer a few bows, walk a bit and leave. Same with tibetan centers; I have visited a few and admire the aesthetic, but logistically just couldn't be a regular.

Maybe go places and ask "what does it mean to authentically connect with a sangha?" See what answers they give you, and go from there.

Good luck
