Microsoft Exam PL-100 Topic 12 Question 35 Discussion

Button trigger tokens are data points that are known and available to the device on which a button flow is running. These tokens change based on factors such as the current time or the geographic location of the device at a given moment.

Note: For example, if you are running a button flow on a smart phone, it is likely that the phone knows the time at your current location as well as the date and your current address. In this context, the time, date and address where the phone is located are all determined at the time the button flow runs. They are automatically available for use in any button flows that are executed on the device. You can use these trigger tokens to build useful flows that will minimize repetitive tasks such as providing your location to someone or tracking how much time you spent on a particular job/service call.
