`sess` package progress

[TinasheMTapera]

Describe the bug
Early adopter of sess here just adding to the data in case its useful! I have one or two projects for which sess installed from the VSCode popup prompt, and it worked perfectly, and others for which it didn't. Today, I tried to deliberately add sess using rv add (I use rv for project package management):

rv repositories active!

It is a bit odd that Connection info not available. How did you launch the R program?
