How do I figure out piano accordion bass button notation in sheet music? ?

Hello, all! So, because of the quarantine, I’ve been getting back into piano accordion. I’ve been a classical pianist since I was five, and have no problem at all sightreading pieces of music or playing the right hand on piano accordion, but I’m still trying to figure out bass button notation in, for example, this simple ragtime piece. Could someone please explain it to me— and is this pretty standard notation? Thank you!  

Update:

Okay this is not letting me post pictures. Sorry.

    You really need somebody who knows accordion to be there with you.  The left hand buttons follow the circle of 5ths.  Two rows of buttons play a single bass note and the others play chords.

    I’m so sorry, I forgot to post the pictures of the piece!  Here:
