In vim, we can implement a vim script, which monitors text changes in details, with listener_add(), listener_remove(), listener_flush(). In nvim, nvim_buf_attach() is available to attach a callback. And I thought I could detach it with nvim_buf_detach() but it looks like not implemented as Lua callback.

I am looking for how to detach/disable the callback in nvim.

:h nvim_buf_attach
• on_lines: Lua callback invoked on change. Return `true` to detach.
:h api-lua-detach
In-process Lua callbacks can detach by returning `true`. This will detach all callbacks attached with the same nvim_buf_attach() call.

So returning 'true' might be a solution but I am not sure how to implement it. Does anyone have a good idea?
