Hello everyone,
I have created a plugin called “showPatientInfo” which shows certain metadata from a volume stored in DB and also shows if any user has connected.
The thing now is I would want to show this plugin via url action (slicer://) as you explained in docs.
Thanks in advance, every piece of help is appreciated.

You need to make a module that connects to the onURLReceived signal from the application. Here’s an example:
slicer://viewer/?download=https%3A%2F%2Fgithub.com%2Frbumm%2FSlicerLungCTAnalyzer%2Freleases%2Fdownload%2FSampleData%2FLungCTAnalyzerChestCT.nrrd
