Custom CDN and Image URI

[neopit]

We are using our own CDN for uploading the image

We need to provide the file extension to the image we want to upload however the URI provided by the Chat has this format

On iOS
"uri": "ph://54D10E18-F060-45A7-8AA6-32D45D11EABB/L0/001"

And the file object do not provide any information about the extension of the file
{"fileSize": null, "filename": null, "height": 1024, "playableDuration": null, "source": "picker", "uri": "ph://54D10E18-F060-45A7-8AA6-32D45D11EABB/L0/001", "width": 769}

Someone knows how can we get more information about the file base on a URI of this format ph://54D10E18-F060-45A7-8AA6-32D45D11EABB/L0/001

I found some posts speaking about using expo-media-library however, in our mobile application we are not allowed to use any expo library
