Ios brave share button with pdf shows half of what other apps do

------ On ios when I have a pdf file in my browser, like for instance
brave does not allow sharing this (or rather copying it to) dropbox or nextcloud.
So when I encounter this I copy the link to Firefox, and then I can copy it to nextcloud.

Because of this issue I cannot use brave as my only browser and that leads to lots of hassle, because I tend to work on in Firefox after that of course.

Any browser should be able to copy a pdf somewhere else IMHO.

So for clarity I ask to add a feature that allows Brave on IOS to share a pdf file on the internet (not a downloaded one) in the sense that you can copy it to some other files stem like Dropbox or nextcloud.
