I need help with adding a Hover-function that lets you display all of the text inside $Description when hovering the mouse over the gallery card in SharePoint Online. Would anyone have knowledge of what to add and where to add it in below JSON?

Thanks in advance.

You can use the customCardProps to create a custom hover card. If you want to do it for the whole card, then you can add it to the first child (the button with a class of sp-card-defaultClickButton. So a very basic one could be done by changing your format to:

        ]   },   "height": 404,   "width": 241,   "hideSelection": true,   "fillHorizontally": true,   "formatter": {
