How can I save data with a prompt ui in Matlab App Designer based app?

I need to save some data generated by the app. I tried the following code but the program cannot locate these variables:

uisave({'app.dataA', 'app.dataB'});

Assign those to local variables and uisave the local variables. app.dataA is not a variable: it is a structure reference or object property reference.
