How to append vim.api.nvim_get_runtime_file('', true) to Lua.workspace.library?

[FalcoGer]

I don't want to manually adjust my workspace library whenever I install or remove a plugin. Luckily vim.api.nvim_get_runtime_file('', true) produces all the paths that nvim's lua interpreter looks for libraries for.
Unfortunately the settings in the coc-configurations are done with a json file and there is no syntax to do a function call there to populate any options, as far as I could gather.
Is there some way to put all those paths into Lua.workspace.library in a different way? Maybe some special string?

From what I found, you can leverage coc#config to change the configuration at runtime (or use g:coc_user_config). This works for me:

vim.cmd([[
  autocmd FileType lua call coc#config('Lua.workspace.library', nvim_get_runtime_file('', 1))
]])
