I have a web portal i use for work and when I try to download a PDF from there, Mozilla asks What should FIrefox do with this file? I select open with Okular and I get a window with KDE COnnect URL handler in the title baraskin device to open. The only option in the drop down is my phone. How can I change this to open on my desktop?

Using Mageia 8 with Plasma 5.20.4
