For your 2021 Chevrolet Silverado you will have to splice into the factory wiring to use the 3rd Brake Light Logic Module # PP20-702 to connect the left and right turn signals, along with the green wire.
You can also combine this harness # PP20-702 with a 4 pole harness like the Hopkins Wiring Harness with 4-Pole Flat Trailer Connector # HM38138.

I am trying this exact setup today. While the break light doesn't blink when the breaks are applied with a turn signal, the light is blinking when I remove my foot from the break with either turn signal on. Is my new module faulty?
