Hi guys,
I want to change a SVG image inserted via URI
First I manually inserted an image in the SVG editor (svg-editor/elements/Image/Load image file).
The selected SVG document is then encoded in Base64 and inserted into the file.
I now want to exchange the Base64 encoded text via the payload.
I think it is the same question as in this case (link), but the solution is not explained here. 
I am grateful for any help!
