Allowed Codes for linux free version

I'm testing out the free version of DaVinci Resolve on Linux, and apparently I can only import .mp3 sound files ( .opus files don't play or show a waveform )
I CAN'T FIND ANY VIDEO FORMATS THAT WILL WORK IN THE MEDIA BIN.
This is confusing and frustrating and seems like a missed opportunity to upsell - if it's intentional and not a broken install it should acknowlege the input and say "format not supported in free version" .
Is there a list of what formats WILL work on Linux in free version?
