2020 Yukon, Denali - front grill options. I purchased a T-Rex Billet grill (P/N 20169) but they say it doesn't fit the Denali? But it fits the Yukon?

I purchased a T-Rex Billet grill (P/N 20169) from 4WP.  No mention of Denali in the install guide, so I called T-Rex and they say their grills do not fit 2020 Yukon Denali's??? Yet, I see them on the streets all the time.  Any advice would be appreciated.
