I do have the key in my wallet - these are the settings. Are your settings the same?
The key must be in the Apple Wallet to function - it will not work with just the RAM app. Looks like maybe you do not have passive entry enabled?
Edit: In addition to the above, your phone uses Bluetooth LE to establish the initial connection with the truck as part of the UWB carkey function (as distinct from the Bluetooth connection to the head unit for audio/cell use). You might want to check to see if Bluetooth is enabled on your phone.
