How to pass configuration options (opts) to plugins?

[TamaMcGlinn]

Many plugins mention that you can pass option in the readme, for example:

"Can be disabled by no_default_keymaps = true option in setup."

How do we do that with vim-plug? I have tried various things like the following:

Plug 'archibate/nvim-gpt', {'opts':  {'no_default_keymaps': 'true'}}
Plug 'archibate/nvim-gpt', {'no_default_keymaps':  v:true}
Plug 'archibate/nvim-gpt', {'no_default_keymaps':  1}

But since there is no mention in the readme, is this even supported?

Traditionally, most Vim plugins are configured via global variables like so

let g:foobar_some_option = 'foobar'

which you would just put in your .vimrc (or init.vim if you're a Neovim user).

But it seems that the new hordes of Neovim-only Lua-based plugins are supposed to be configured via some Lua code. So you should directly call the Lua code in your configuration file, not through an option of vim-plug.
