Burn ISO to DVD in macos 10.15 Catalina

https://support.apple.com/guide/mac-help/burn-cds-and-dvds-mchl8addfd95/mac says it works on Catalina, but when I select "Burn Disc Image" after selecting the .iso in the Finder, no windows opens, nothing happens at all. The same machine, a MacBook Pro (15-inch, Mid 2012) running Mojave works in exactly the same manner. (The two machines were exact copies of each other, except the amount of RAM, before I upgraded one to Catalina for testing.) The same thing happens on a vanilla install of Catalina on an iMac with a USB burner attached. I can't find anything interesting in the console.log either.

I know optical drives are not very common, but I still work with old computers and booting from USB is not always feasible. If it is planned not to work, then the option should be gone from the Finder.

If you are not afraid of the command line, you can burn ISO images from there where the Finder fails. For example, to burn the latest Ubuntu ISO, load Terminal.app, and there you would type the command (in bold; the resulting output is below):

hdiutil burn ubuntu-19.10-desktop-amd64.iso
