Is there any way I can clear Camera > Recent pictures?

[The0xArchitect]

As the title, is there anyway I can clear the recent photos that I've taken with in-app camera?

All the recently taken pictures are stored there for no matter what. Interestingly, I don't even know whether to call those pictures recent at all. There are 2-3 months older pictures as well.

The location: Attach menu > Camera > Recent

Here's what it looks like:

What have I tried?

• Tried clearing cache from inside the app (Settings > Storage > ...)
• Went to system folders and cleared caches (including Library/Group Container/...)
• Tried uninstalling and re-installing

Turns out nothing worked out to remove these pictures.

Question

1. Where are these pictures are stored?
2. How can I clear them?

Thanks!
