In KDE you can access this sort of thing with the built-in GUI file manager right out of the box. You don't need a third-party app.

1. Open Dolphin (file manager)

2. Right click in the Places section on the left to add entry

3. Type `fish://<the-address>`

4. Click OK

As someone that's spent multiple decades living on the command line for almost all my file management... sometimes I still open the GNOME file manager because a GUI makes a select few tasks simpler.

It's all about the right tool for the job. Some people are more comfortable with a GUI for the majority of file management tasks, some people are more comfortable with the CLI for the majority of file management tasks. It's just a bit silly to be a zealot and put yourself through a lot of pain if one of these isn't optimal for whatever you're trying to do.
