Creating descriptor for Trezor

I’m trying to create a watch-only bitcoin descriptor wallet in Bitcoin Core. How do I construct a descriptor wallet from my single-sig Trezor wallet? I have the XPUB, but I’m not sure what to pass as the other parameters.

I’m not sure if Bitcoin Core has this feature.
The watch-only bitcoin descriptor wallet I created uses other software on the Android phone. By importing xpub, it can generate new unused addresses of its own imported wallets at any time.
