I have a Thinkpad T14s (AMD) with the WWAN card offered directly by Lenovo.
Modem manager can't seem to detect the card though?

having seen This post, I ran lspci

However, when I run 'Modem-Manager GUI' I get a blank screen,
and when I run 'mmcli' I get 'No modems were found'.
I'm about 3 years deep into Linux but this is my first time working with WWAN laptop stuff so don't know where to go from here.
I do also see from this post that I'm at least not struggling alone, though I'm not sure if there's anything more recent that I'm missing. I do also note that other posts on a similar vein are talking about using usb modems rather than internal cards, not sure if theres a practical difference.
