render replies natively

### Your use case

#### What would you like to do?
see replies from discord rendered as a reply in element ios

#### Why would you like to do it?
so i can understand the conversation

#### How would you like to achieve it?
copy how the react SDK handles replies

### Have you considered any alternatives?

deleting the element ios app and only using element web?

### Additional context

I am using the t2bot discord bridge to matrix rooms.

When someone replies on discord, the reply is only correctly rendered on element web (not on element ios).

The information I got was "the mobile app expects a fallback representation which isn't present in the events". But however the react SDK handles this seems to be how it should be handled, because it works correctly in element web.

No Element iOS file or test is named. Start by comparing how the React SDK and Element Web render replies from the t2bot Discord bridge, then trace the corresponding reply-rendering path in Element iOS and inspect the missing fallback representation. Done means Discord replies render natively as replies in Element iOS.
