Using Bitcoin Core wallet as "watch only" for BTC held by Trezor T

[Abuliglig]

Hi all,
I'm new to Bitcoin and over the past week started to run Bitcoin core on my laptop. I would like to make better use of it., and was wondering if there is a way to actually use Bitcoin core as a "watch only" wallet to keep tabs on the coins held by a Trezor Model T.
I'm not a programmer etc, just a simple guy, so would very much appreciate any simple step-by-step explanation that is easy to do. If this process is in fact complex then I don't think I want to try for fear of losing my sats or ruining my laptop etc.

400GB free.
my RAM is 8GB
Intel Core i5-4210U CPU @ 1.70GHz   2.40 GHz
Bitcoin Client Software and Version Number: V0.20.1
Operating System: Windows 10

Thank you.

There is [1]. It's not included with Bitcoin Core so you'll need to set it up yourself. It's basically just the script extracting the master public key of the HW wallet and putting it into Bitcoin Core. It could be done manually without the script, if you can extract the master public key yourself.

The synchronization would take quite long and leave you with much lesser storage space (unless you prune it). Electrum would provide a faster and a hassle free way to do so.

Unless you absolutely want to use Bitcoin Core with your Trezor, I'd also recommend using Electrum instead.

The setup is pretty straightforward:

(Just ignore the "How to install Electrum with Trezor device on Linux" bit, everything else applies to Windows just as well as any other operating system)
