Disable indexing progress reports

^{Originally posted by miquecg July 15, 2022} Hi,

I'm using coc LSP client plugin on vim with erlang_ls. Every time I open a source file or type in a buffer several progress bars pop up reporting indexing of the project files. This is a bit annoying and first time I see it happening. Other Language Servers I tried, mainly Gleam and Elixir ones, don't show this behaviour.

I've posted a discussion on coc.nvim repo but didn't find a solution yet, so I'm asking here just in case there's a configuration setting for erlang_ls to disable this.
