Asynchronous execution of call Activity

In above bpmn flow. I have condition which triggers Do-recovery on condition(transaction.status == pending).
And If recovery is success then it triggers UpdateTripAndSendNotification.

But in this flow, when transaction.status == pending, I want to call Do-recovery callActivity and finish the event. I don’t want to wait for Do-recovery to finish.
Asynchronously if do-recovery gets success, remaining postbooking steps will be executed.
I am new to BPMN, can you please suggest How can I achieve this
