Zoom Apps side panel resizing

Hi, I'm creating a Zoom app.  I am noticing that I only have 2 choices collapse and expand.  The collapse is too small and expand is too big.  The user can re-adjust the size manually.  But I would prefer to resize it to the right size for my app by default.  Is there a sdk function or api I can use to do this.  I am using plain javascript.  Any suggestion would help.  Thanks.
