I just tried to add my first example flow to the Node-RED library - and failed.
Text looks fine, but I am unable to insert images by URL since modern browsers complain about CORB or CSP violations when trying to display the library entry...
For that reason, I tried to update the underlying Gist (which was told to be owned by me) but GitHub did not authenticate me when trying to "push".
Thus: how can I access "my" Gist (and add images or other files) - or add images (by URL) in any other way?
Thanks in advance for any help!
