@sunilsinghchaudhary00 have you managed to solve this question? How did you do it?

[sunilsinghchaudhary00]

yes i found a workaround the thing is you have to do code on android mainactivity which tidious and also its not good idea using like that because it is executing many times so good way to do this is get the silent data using firebase not with onesignal as onesignal is for only notification focused use Firebase for that
