Context can be applied within Flows using branches.
Branches are extremely useful when you can expect different input from a user. The following example demonstrates this with a question Would you like to Takeaway or carry out that expects 2 different answers.
You can create branches by dragging and dropping triggers on top of each other. It will work with intents, but also for events, timers or unknown triggers.
Branches can only exists within flows as follow up steps, and cannot be created for the first step. If you want to achieve that, simply add a another flow with the trigger.
