How to execute commands that we can only use them in normal mode?

I'm using coc.nvim as Intellisense engine for neovim. I want to use vim-quickui to remap it's functionalities:

But most of it's command only execute in normal mode:
https://github.com/neoclide/coc.nvim/blob/master/doc/coc.txt#L663

My question is how configure vim-quickui to execute coc.nvim commands. Imagin i have this menu:

call quickui#menu#install('C&oc', [
            \ [ "&config", 'CocConfig' ],
            \ [ "code-&action", '<Plug>(coc-codeaction)' ],
            \ [ "codeaction-&selected", '<Plug>(coc-codeaction-selected)' ],
            \ [ "co&mmand", '<Plug>(coc-command)' ],
            \ [ "dia&gnostics", '<Plug>(coc-diagnostics)' ],
 \ ])

But it won't works and gives me this error:

Error detected while processing function quickui#menu#open[8]..quickui#menu#nvim_open_menu:
line 94:
E488: Trailing characters: (coc-command)
Press ENTER or type command to continue

I don't use coc, try:

[ "code-&action", 'call feedkeys("\<Plug>(coc-codeaction)")' ],

It works! thank you.
Edit: This one works too:

[ "code-&action", 'exec "normal \<Plug>(coc-codeaction)"' ],
