How To Show Up On Suggested Users?

I've noticed that's when you go on accounts with decent amounts of followers a suggested users triangle is there. It looks like this

I'm wondering how does one get on that list? It's different for every user, surely there's something that determines who's on it, right? I have an 80k account and I checked a lot of users in my niche and none of them had me on it.

From what I gathered, you are on a suggested user list depending on the users that follow you, you'll only be able to see that if you log in as another instagram account, but I believe it's totally random.

Im pretty sure it's only on larger accounts. I have a 73K account all real followers etc. and my friend punted out that the suggested feature is visible on my profile. Also, on Android the suggested feature only comes up AFTER you hit the follow button where as on IOS the downward arrow is visible when the profile loads
