How to edit raw photos in lightroom mobile

I'm on my vacation and want to use lightroom mobile for editing raw images from my Sony Rx100v. My license should allow that, but I can't find out how to do this.

I import photos from Sony Play memories into my sd-card. I have 'use sd-storage' and auto-import for raw enabled, but my photos are not showing. I can't find any way to point directly where to search my photos, but i know the location.

My internet connection is very bad, so it is very difficult to find any information. I don't even be sure if Sony is supportrd by mobile version.

I would appreciate any help on this matter.

I would really like to use my sd-card and dont have multiple copies of my images, since there is not enough space on my device.

It would also help to have a link for user manual. Not for online one, because internet pages just timeout and never get ready.
