If you want the displayed image/text/audio to disappear automatically after a delay, you don’t need a toggle button, but you can use a shared action with these commands:

     Show    xxxx
     Delay Next Commands by …..secs
     Hide    xxxx

I posted an answer, but it is waiting moderation because I inserted links to blog posts created in this same portal  If you want you can search in this portal for ‘hotspots’. I posted recently two blog posts about Forced Hotspot clicking, where you’ll see two workflows. The first post is for a non-responsive project, the second one for a responsive project with fluid boxes.

Use a shape button (there is circular shape), which is a shape with the option ‘Use as a button’ activated in its Properties panel. You don’t tell which version you are using, nor if you want to create a responsive or a non-responsive project. These two blog posts explain two workflows to ‘show’ and ‘hide’ a popup. That popup can be an image, a text container, and you can always attach object audio to them, whether they are individual objects or part of a state.
