For reference: This is how to hide private information from text/plain when using widgets

[kolibril13]

Today, I was wondering how to not accidentally commit my open AI key when passing it to a widget.
Even when I import it from another python file that is git-ignored, it would still show up as plain text in the text/plain notebook metadata.
Therefore, here's a solution I came up with, hope that this will be useful for other people as well! :)

class MyPrivateButton(ipywidgets.Button):
    def _repr_mimebundle_(self, *args, **kwargs):
        mimebundle = super()._repr_mimebundle_(*args, **kwargs)
        mimebundle["text/plain"]= "Button Widget, all private info got removed!"
        return mimebundle
    
MyPrivateButton(description="My Secret Key")

I am confused, why we need to put a secret in Button's description in first place? And also, your MyPrivateButton class is not showing a button.
