The main difference between the Transparant button and the Text interaction is that the Transparant button will not be visible, but the Text interaction will be.
Generally, the Text interaction is more frequently used. That’s because you can add a message to let the viewer know to click on the button, for example: “Click here for more information”. Of course, you can also create a button using graphic design software and add this as an image.
So what’s the benefit of a transparant button? Well, it’s possible that you’ve created some fancy buttons when you were editing the original video. You can then use the Transparant button to make these clickable. Moreover, you can use it to make a logo or item clickable. For instance: “Which container would you use? Click on the correct container.”
Transparant interaction: invisible and no possibility to add text.
Text interaction: visible and possibility to add text.
