How can I pull my RAW photos out of "PHOTOS" on my MacBook Pro into Lightroom and have them remain RAW instead of JPEG?

If I did do that, would they migrate as RAW? I have such a meticulous library in PHOTOS that I hate to disturb it. My problem is that when I export a RAW picture from PHOTOS onto the Desktop then put it into Lightroom, it only shows up as a JPEG.

When I choose a RAW photo from PHOTOS and go to export it, is there a button that allows me to export it as an unmodified original? I'll check that out. Also, the above link tells me that it supports my camera which is a Canon 6R. I'm not sure that it actually says anything about PHOTOS. I know that if I start now using Lightroom to catalogue my pictures, I won't have any problem. I was just hoping to be able to edit the RAW photos I already have in PHOTOS with all the info that RAW brings in.

I will start using Lightroom from now on, but I have thousands of past RAW photos on my PHOTOS app. I'd like to use all of the RAW data on some of those.
