Cluster ribbon torn from pcb. How to reattached

[rob h]

Hello guys,

W638 Vito Marelli cluster. Mileage job.
i fail to connect using avdi on the table.

After i opened it, i acciidentaily loosend the ribbon.

I aplied so heat, and was able, to make it a bit sticky.
It does not stay in place.

I consider creating a clamp, to press down this ribbon.
But there is no space, to leave that on. After rebuilding the dash.

How can this be fixed?
Glue? What kind?
More heat?

Any advise, please share
