For Deeplink with regular expressions, you can choose Type of variable: Array or String. The array will be useful when you need to get not only the value of Deeplink, but also its individual parts. The first element will have the full value of Deeplink, the rest elements will have the group value. For example, regular expression: triforce_of_ (.+?)$ and Deeplink triforce_of_wisdom has such an array: [triforce_of_wisdom, wisdom]. In this case, String type writes to variable string: triforce_of_wisdom.
