Describe the bug

Debug Console Suggestions are not working

Steps to reproduce the behavior:

Here is an example of debug console suggestions working with the Python debugger

[shellwhale]

It looks like there is already Delve support for this https://github.com/go-delve/delve/pull/3004

[hyangah]

The delve feature is for dlv cli. I don't know how this can be implemented on top of DAP. Or is there VS Code specific capability to utilize?

Delve DAP currently does not support this capability. cc @suzmue
