Creating backup from dead screen

My Pixel 5a with CalyxOs has a hardware issue, the screen has died. I can connect it to my Linux computer though, and have been able to save pictures, etc. Is there a way to grab my AntennaPod data WITHOUT creating the opml export using my screen? Thanks!

If you have ADB with root access, you could look at the database in /data

Unfortunately I cannot, this phone was never connected to this PC and it wants me to confirm via the device
