How to reactivate my store after a false DMCA claim?

I have had this store for 3 years now, made over muktiple 7 figures

i have a bit of a following in IG where i talk about shopify and ecommerce

so my followers are mostly dropshippers as well

i accidentally got my store leaked a few days ago, and someone who had their store for less than 6 months sent a false dmca and my store got terminated

im fully ready to get a lawyer involved but i dont know where to go

i need my store activated again and up and running this is my main source of income and its not fair for this fake dmca to do this

i need assistance
