Newbie question about the DFPlayer Pro mp3

I am new here and also new to hobby electronics. I have a basic question about the DFPlayer Pro mp3 player.

I have it wired and working in my project but have one question. I would like it to auto play the track I have loaded when it first receives power. I do not want to have to press the play button that is on the board or control it with an Arduino. I just want it to play the sound effect when I turn on the power switch to my project. I don't have a problem with the wiring for the power of the attached speakers, just getting it to auto play.

I have looked through the wiki information and could not find the answer.

Thanks!
