In order to use it, you must first enable the plugin in the Project by going to the Plugins tab of the project properties:
Most of the public RSS feeds (press..) will work locally but won’t be available when the PWA is loaded from an http/https location.
(This is due to the Security policy of the RSS feed provider).
Make sure you have the right to access to an RSS feed before implementing it with this plugin.
Once the plugin is enabled, then you can drag&drop it on the page by choosing "RSS Reader” from the widget list (Miscellaneous Section)
By Double-clicking on the Widget, you can access to its properties:
The RSS feed http address (without “feed:”, for instance "feed:https://www.myrss/" should be entered as "https://www.myrss/“)
Add or not a user Searchbar (full-text)
Show or hide the publication date in the list
Show or hide the Description in the list
Show or hide the Image in the list (When relevant)
Choose here the image size in the list (in pixels)
