PowerApps - Camera Control and Form

Question

I have an application in which I have to record payments which are sent to the customers,

So, I have a Form control and a Camera control, I want to save both of the information into a SharePoint Document library, because of the Picture control ( it can be saved in document library. ).

I have a flow for the Camera control to save the taken picture into the document library, but I am having some issues.

1. I am unable to save both the form details and its related camera picture with the same ID into Sharepoint.
2. The Camera isn't displaying in full screen to capture the picture.
