AI Summary: The task requires creating a custom regular expression and `getTriggerData` function for the `react-native-controlled-mentions` library (v3) to maintain backward compatibility with the v2 mention format (`@[John Smith](123)`).

The solution needs to ensure correct rendering of the mentions within the `TextInput` component.
