File Upload Persistence When Navigating Away From Chat Screen

When sending a file larger than 100 MB, if the upload is still in progress and the user taps the back button to navigate out of the chat screen, the file upload does not persist. Upon returning to the chat screen, the file disappears and is not sent.
It would be helpful to have the upload continue in the background or resume when returning to the chat, ensuring that large file uploads are not lost due to navigation.
