What chain is compatible with the SRAM RED 36T Max rear derailleur? Can I use an Eagle 12-speed chain with this derailleur?

SRAM RED and Force Flattop chains are the only chains compatible with the SRAM RED 36T Max rear derailleur. Please use the chain specified for the rear derailleur and cassette. Eagle 12-speed chains are compatible with Eagle cassettes and rear derailleurs only.

You can find the AXS compatibility chart here.
