The claim process of any time-based reward was designed to be extremely easy and intuitive to let your users get familiarized with it in no time. This process follows the next steps:
1) When an user is able to claim, he will see the counter at zero and the claim button enabled.
2) After click the claim button, the add-on will randomly generate the rewards based on the rewards setup and will display a pop-up letting him know which rewards has earned.
3) The time-based reward will get completely reset, the counter will start to countdown again and the claim button will get disabled.
