Apps and websites logged into your account

I let a small engagement group be authorized on my account. I rarely use this group, but I did once and coordinated 11 comments. I see them listed under APPS and Websites on the desktop version of instagram.

is this going to cause me problems? I never understood why they needed my info, although the goal was to get comments timed at same time of post but why did they need to log in as a app/website to accomplish this? I used them for the 2nd time yesterday for 6 comments, and now it seems a soft ban I can not figure out the reason

can anyone explain for what exact reason an engagement group needs API access to my account.
this telegram bot group is coordinated that comments are issued at exact times for maximum affect although the group is still very small …12-20 people
thank you
