Where do files, airdropped onto an iPad, end up?

Friends

I have buiIt an app for iPadOS using Swift. I am sharing data with the iPad using Air Drop (or email attachments). CSV, or JSON, formatted files

I have set the XML in Info.plist. My question is: Where does it end up on the iPad? Using FileManager, how do I read it?

<key>LSItemContentTypes</key>
			<array>
				<string>public.comma-separated-values-text</string>
				<string>public.json</string>
				<string>org.openxmlformats.spreadsheetml.sheet</string>
</array>

Where do files, airdropped onto an iPad, end up?
