// Initialize Interface

Set sensor_msg::msg::joy to interface. Then you can access any button state via the interface.

void Example::onJoyCallback(sensor_msgs::msg::Joy::ConstSharedPtr joy_msg) {
ps_interface->setJoyMsg(joy_msg);  // set joy message to interface

// When Circle Button Pressed..
if(ps_interface->pressedCircle()) {
 // You can hook action here
...
