The "Hide once viewed" option is available on the Professional plan or higher, and will only work for the following embed types:
Note: This feature will not work with the option to show the popup "On button click".
Good to know:
This feature is limited to a user's browser. This means that if a participant decides to use a different browser or simply clean the browser's cookies, they will be shown the popup once more.
The "Indefinite" setting on the duration means that the user won't see the popup for as long as possible. This is due to many browsers having a maximum cookie age (eg. Google Chrome has a 400 day maximum cookie age by default).

You can also use the "Hide once viewed" and "Stop showing once completed" features together.
