But I cannot see any syntax coloring and don’t know how to compile a TeX file.
Would you please help me more?
I think you also need to choose the context color scheme

Yes, syntax coloring works after choosing the context color scheme.

I find a following task file to compile a file from vscode, but it doesn’t work.

Here is the error message:

/bin/bash: context: command not found

The terminal process terminated with exit code: 127
