php. How to get a list of a user's Instagram followers?

Question

PHP

There is a task in the Telegram bot, after the user enters his nickname, to check his subscriptions.
I use Yii2 and https://github.com/postaddictme/instagram-php-scraper .
At the beginning, everything was fine - but after connecting a larger number of users to testing - there was a problem with an error received from Instagram about exceeding the limit.
As an option, they began to connect from different accounts (in order to bypass the limit on a specific authorized user) and use a proxy (also random).
As a result, we still get an infinity of 429 errors (rate limit), as well as unstable authorization - i.e. out of 5 created accounts of the same type, 2 are stably authorized, and 3 are either authorized once or not authorized at all.
I was looking for analogues of the library - but I did not find anything sensible for the task of obtaining subscriptions.
I looked in the direction of the application - but, as I understand it, the requirements there are very strict + you need a screencast for the finished application, and based on the fact that the work will be in the Telegram bot, there is a big risk of not passing the test.
Who ran into the problem - how to solve? Maybe some other libraries...
Thank you.
