I've used linux since the 1990s. Was friends with the founders of LinuxCare, met Torvalds. blah blah blah...
Since semi-retire from ops... and basically using windows for a few years without need to manage a linux box, youd be FN surprised how quickly basic knowledge evaporate at my age when not in use. I had to fn lookup how to add my keys to a box again.
(After a 3-month long panel-interview with Google's Net Eng Team back in the day - my final panel question was:
"OK how do you do a global search and replace in VI?"
I *blanked* -- and I stated... "UH.... I'cant recall - id just google it"
They all laughed.

@OP -- look at the remote SSH extension in VSCode/Positron etc...
Its a really good little file/function/SSH manager.
Though Ill take a look at this.
