Hi Steven,
Great question. Yes, you can use the "Timeout" feature under the button group settings. For example, in the screenshot below, the button will start as visible, and will automatically hide in 10 seconds.
Note, since I set "Trigger only once" to disabled, it will behave like this on every page load (i.e. the button will show and then hide after 10 seconds). If you want it to only show the button once during the user's entire visit, it will only show once and then hide after 10 seconds; it won't appear again for the rest of the user's visit.
I hope that helps! Please let us know if you have any other questions 🙂
Cheers,
Tony
