Thanks, but the question is more related to creating the set up. I know about the psbt part.

This.

You could also do it airgapped. Sign the TX on your device with an SD card then drive or send in the mail to signer no2. 

Sparrow 2.2.3 is now available:
https://sparrowwallet.com/download/

I have Sparrow 1.8, and I am not able to see an option to import the details from the signer that is in another location. I solved using 2 mobile phones and the web cam from the laptop, but is not the most user friendly way...

Some questions about Multi Sig wallets

Yes, you can create a 2/3 with people in different places using sparrow, you'll just want a secure way to get details sent from the remote person to the person creating the 2/3 wallet with sparrow. Maybe use signal or protonmail to get the details over. Try it out with a test wallet setup first, don't be afraid to play with sparrow, I've found it to be a lot easier than it may look at first.

Yes, you can import your multisig xpub to create a watch only wallet with the app/wallet of your choice.
