Is it possible to include the commenting feature in the Community Edition?

[TuringTux]

Overleaf.com seems to offer the feature to add sidebar comments for free, which is nice.

However, the self-hosted Community Edition does not include the commenting feature (see also #1036 (comment)). Is it possible to include the commenting feature in the Community Edition?

Expected Behaviour

A self-hosted Overleaf instance offers a feature to comment on text segments.

Observed Behaviour

It doesn't.

You can try to develop it by yourself, or purchase server pro.

Btw, I think commenting feature is not something difficult to imply, the core code is open-source, just need a proxy.

I implied this in my own server, as image shows:
