Hello!
I would like to make an app, that looks like this.

And I want to get data from Marvin not via upload button ⬆️ (that's in the Marvin window), but I'd like to make my own button and trigger callback that get data from Marvin and do some predictions.
I see that I have to press ⬆️ button to load data from Marvin to download attribute, but can I somehow automatically write data from Marvin to download attribute on update of Marvin window?
