Did you know that in the info articles you have the possibility to include videos with a preview function? The requirement for this is that the video has been uploaded on a video platform.
Write the article as usual and insert the URL of the video into the text.
Now you only have to mark the URL and press "unlinked".
Then you define the visibility, define the category, save and publish the info article.
If you open the info article in the app, the video will be displayed.
