Overloading a keycode to accept copilot suggestions only when applicable

[peshevv]

Hey all,

Is it possible to utilize a keycode for accepting suggestions that is only taken over by copilot when a suggestion is present? I've bene migrating my copilot usage over from a few IDEs, and that is usually how they function.

To make this more concrete: If I chose to map suggestion.accept to <TAB>, is it possible to insert 4 spaces if I press <TAB> in insert mode if there is no copilot suggestion present?

I've taken a look at the source code, but I think this may be an nvim limitation?

Realizing that copilot.nvim has this functionality by default for another example
