Background downloads dont work in iphone app

If I leave of exit the brave browser even without removing it from multitasking my downloads fail.
If i have any file/files downloading, i cannot go to my home screen or switch to another app, if i do so then when i come back to the brave app my downloads have failed. But in safari the downloads continue even if the app is closed.
This makes it impossible to download large files from the brave app

I’m facing the same issue in iphone 14 pro (ios version 16.4.1). Please help.
