How to remove the digitizer (no glass) from OLED panel?

I tried to do a glass-only repair and remove the OLED+digitizer+polarizer from the (cracked) glass instead of removing the digitizer+polarizer+glass from the OLED panel. It didn’t go well… I have a polarizer (I think) that’s flaking off and a small bubble imperfection on the edge of the digitizer. The display and touch both work, but I can’t reassemble it this way. Photos attached.

How do I remove the digitizer from the OLED panel without ruining the OLED? I tried heat once and it burned the OLED, presumably since there was no glass to act as a heat sink. What’s the best way to do this? I really don’t want to ruin the panel… they’re so expensive. Thanks in advance!
