How to execute Julia code in VS code editor with Julia Language Support plugin?

In VS code,

with the Julia Language Support plugin installed,

with Julia installed on my macOS,

% which julia
/Applications/Julia-1.7.app/Contents/Resources/julia/bin/julia

 When trying to run (Shift-Enter, or RUN icon) Julia in VS code I got this error:

command 'language-julia.executableCodeBlockOrSelectionAndMove' not found

Solution

• I reinstalled the VS code plugin
• I rechecked the PATH (see above)
• I CLOSED and RE-OPENED the VS code

And voila, it works. Not very scientific, but I am happy.
