Yes, but here comes the problem: where would I send this request? Instagram notes no public facing physical address for my country and their support e-mail just sends back automated replies.
I would send the request both online and by tracked post with a proof of delivery. In the end your lawyer would do the same thing and charge for this at an hourly rate.
"The data controller responsible for your information is Meta Platforms Ireland Limited, which you can contact online or by writing to:
Meta Platforms Ireland Ltd.
4 Grand Canal Square
Grand Canal Harbour
Dublin 2 Ireland"
The "contact online" link leads to the following form: https://help.instagram.com/contact/186020218683230
