How to add Liftmaster 828 LM Internet Gateway in Ring

Hello I have the Liftmaster 828 LM Internet Gateway in Ring and I saw somewhere that some users they could add to Ring. I have running it in MYQ application from chamberlain without any issues all is perfect and also I followed the tutorial from RING to connect the MYQ app with RING but when both apps are linked simply this device are not detected and I can’t select it to be updated in RING. How can be added to RING the Liftmaster 828 LM Internet Gateway in Ring? Thank you
