How to reload data in mashup

[#1]

Hay everyone,

can anyone help me out how can reload data in mashup from database "MySQL",

I'm using Qlik Sense Desktop and created some mashup,

So the real problem is that I'm using Qlik Branch Extension to reload data in sheet and its work fine, but its not working in mashup

I want to use button that is in the snapshot "Reload Data" btn to reload data(this dashboard is connect with MySQL database)

what script or method should I put behind "Reload Data" btn to reload data.
