Create new files inside a collectives page

[tawfekk]

Describe the solution you'd like
Userstory: My team and I would very much like to be able to create new files(documents, spreadsheets etc.) directly inside a collectives page --> these files should then reside in the .attachments folder exactly as when you upload an attachment manually.

This would be useful if for instance you had a page about X - and you would want to create a new document relating to X and have it all stored in one place.

I am a bit unsure about how this could be implemented in practice, maybe a new option in the "Insert attachment" menu called "create new" or something like that?

Describe alternatives you've considered
An already working (but rather complicated) alternative is to create files beforehand somewhere else in Nextcloud, and then either upload them to the collectives page as an attachment or linking them in page with the "insert link" menu.

Additional context
I hope it's possible and within the scope of the purpose of collectives:-)
