C++ g++ VSCode bash help

I am attempting the basic Hello World! code for C++ using the bash terminal of VSCode… but getting “g++: command not found” in bash. I assume some sort of extension compiler is used that is not shown in the video given here: https://www.youtube.com/watch?v=hKCYP4HWisE

I really like using bash and VSCode and would prefer to compile that way over others. Can someone tell me what extension is used in the video so that the I get the desired result.

I have installed the C++ extension and a couple more that were recommended by VSCode and restarted VSCode so that is not the issue.

Thanks in advance!
