I have create a SharePoint WebPart as well as a CommandBar-Extension using SPFx. I used the yeoman generator to schaffold the application and finally created a sppkg-file I can deploy to my app-catalog.
However: I would need some kind of configuration for the WebPart and the Extension. If it would only be the WebPart I could work with the WebPart property pane, but for the Commandbar-Extension this doesn't work.
Is there any way to have some kind of configuration-page/setup-page where I could store some value for e.g. as a property (in the site property-bag)?
