@russian-dima I just found out that wix does not support importing backend functions into custom elements.
I guess that’s why you pointed out the interaction between page and element → thnx.
Currently already trying to map a custom event for the interaction between page and custom element to handle the call towards the backend script.
I guess then I can some how get a blob?!?
Workaround with event is not so nice, I’ll just archive it under wix-illities (thnx though)
