I am trying to use image from my google drive in google script so that it can be used as a header. But it's not working and just shows small thumbnail icon at top. I am using the following code to achieve this:
var gridLogo = app.createGrid(1, 1);
gridLogo.setWidget(0, 0, app.createImage('https://docs.google.com/...'));
Dots are put in above link for privacy purpose.
I have published the site as Web App and can be accessible by myself.
Is there anything I am missing? Please suggest.
Thanks
