Based on my research your 2019 Buick Regal TourX doesn't come from the factory with a pre-installed trailer wiring connecter but one can be easily added. For this I recommend the Curt T-One Wiring Harness # C56389.

This custom harness simply gets plugged into existing ports behind the driver and passenger side tail lights. After running the hot lead up to the battery you will have a fully functional 4-Way connector to connect with and power a trailer's basic signal lights.

I have attached the written installation instructions that you can also look through along with an installation video on a similar 2018 model.

The Curt Class II Receiver Hitch # C12173 that you were also looking at is a perfect choice for your Buick and it will line right up to existing holes in the frame rails for a simple bolt-on (no drill) installation.
