How to access connect app in page comment section?

Question

I can access my app in page (in edit mode)  using `/` command but can't do the same in comment section.

I can do this in confluence DC and that works.

I tried updating the `categories` section and made it empty but that didn't work. As per the doc, if we don't pass any category then by default it takes `All`.

This is most likely due to not allowing apps to work in comments due to nest macro concerns.
