Tplink RE200 doesn't see 5G network

I have an TP Link RE200 range extender. When searching for networks to extend, it successfully finds the 2.4g signal from the TMobile 5g gateway. Even if I go into the Tmobile gateway app and add a separate 5G specific network, the RE200 doesn't see that 5G network. The RE200 does see other 5G networks in the neighborhood, just not the one from the Tmobile gateway.

Is there a setting somewhere that might let the RE200 to see the Tmobile gateway’s 5G network?

Or can someone recommend an extender that definitely recognizes and connects to the Tmobile gateway's 5G network? Gracias.
