function to toggle panel

Hello,

First off, thank you for this awesome plugin! Just starting to use it in certain situations and it amazes me how it works.

I recently created a toggle function to disable/enable copilot:
```
" custom global var for toggle function
let g:copilot_enabled = v:true

function! ToggleCopilot()
if g:copilot_enabled
Copilot disable
let g:copilot_enabled = v:false
else
Copilot enable
let g:copilot_enabled = v:true
endif
Copilot status
endfunction

nnoremap c :call ToggleCopilot()
```

And wanted to create something similar with `:Copilot panel`.

Any input in how I could achieve this is appreciated?

Thank you,
Dave
