Hey there,
And welcome to our community 
The current Perforce integration has been deprecated and, unfortunately, we’re not in a position right now to update the code.
A new Perforce integration is under consideration on our roadmap under Considering—add your interest and the Product Team will keep you updated on news.
In the meantime, @jhultgre shared out their own updates and code on the forum in this post.
I hope it was helpful,
Linda
