How can I send onesignal notification between two devices

Question

I want to send a onesignal notification from a button in android studio to another device using device tokens. But I am not getting it. What is the proper way of doing?

I want event to be trigger by the button not by onesignal dashboard

SendNotificationBtn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    
//code to send notification to another device.

                }
            });

Use OneSignal REST API (see Send to Specific Devices in the documentation)
