How to remove this connector?

I’m trying to remove this connector from the HMI in my Impala and I can’t for the life of me get it to come out. Whats the trick?

Lift the red lock tab. You might pull it off completely. Find the primary lock tab built into and the same color as the connector. It is that rounded thing next to the red lock tab, I think. Press that towards the connector body and pull. Should pop right off.
