When you click View Details, you can find you can take action as required. You can find the different types of jobs with the different actions to take here.
You will also receive an email about the job on your email address listed, where you can accept or reject the assignment.
After the assignment is confirmed to you, you can see it on the Schedule tab (icon with the calendar). The ones with the dot (.) underneath the date indicates that you have an assignment on that day. If you tap the date, you can see the details of the assignment on the page as shown on the screenshot below.
