Hi. I am a software developer who general does a fair amount of web-scraping and API development. In this particular case, I would suggest doing 2 things. First, it might be worth checking if the company has a public API as scraping is generally forbidden and included in the terms of service.
In the case of Instagram, they do have an API which can be used to retrieve information about public users. The process is a bit long, but there are clear instructions on the Meta API documentation page. You can check this link for more information related to your specific request.
If you have more, questions, please feel free to get in touch.
