Smaller engagement groups?

Hey there community,

so first of all I would like to mention that i'm still quite new to this whole instagram growing, however, I was wondering where exactly I can find smaller engagement group for a personal niche. I've just discovered telegram and all I can seem to find is all these huge groups with thousands of members. (..found an 10 month old reddit post from 2017 where the biggest are listed..)

Should I just try to join these very big ones, or are there actually smaller once?

Maybe I should also mention that I'm definitly not some kind of 40k+ followers personal account, all im looking for is a small start, some likes, some comments, some follows, all that good stuff you know.
Have mercy with me i'm still super new to this and really trying to learn the way this works. Thanks!

You can DM to pages that are similar size and have similar engagement rate to yours and ask if they have a DM group or if they want to join yours.
