Positron not finding R interpreter in SSH

Session details:

R 4.5.2

Issue:

When I tried to open an R file from a GitHub repo cloned to my HPC, Positron could not find R as a session interpreter, even though R is installed on my University's HPC. Below is a video showing the issue. Note that

1. This issue also occurred when I tried to run a regular R file that was not associated with a GitHub repo.
2. R runs fine for me in Positron when I am not using an SSH connection

Steps to reproduce the issue:

1. Start SSH connection to HPC
2. Clone a GitHub repo into the HPC or simply open an R file
3. Open an R file from the repo and try to run

Expected or desired behavior:

Positron should find the R version installed on your HPC as the session interpreter.

The error message I saw when I tried to run 2+2 in an R code was "Cannot execute code because there is no registered runtime for the 'r' language."

Start by reproducing the missing R session interpreter over an SSH connection to an HPC system, comparing it with local execution. Trace how Positron discovers and registers the installed R runtime in the remote session; done means an R file can execute code remotely using the HPC's installed R version.
