About POTY'22 activation

I have registered for POTY'22 and got invitation mail, as I already have a 3D experience ID , I logged in and posted a query....but today I received a mail claiming to have a pending activation "Based upon your request, you were invited to the 3DEXPERIENCE platform. It's been over 2 weeks and you still haven't connected to the 3DEXPERIENCE platform. "

What am I supposed to do?
