My Goal
I want to make my Databricks Notebooks more interactive and have custom HTML/JS UI widgets that guide non-technical people through a business/data process. I want the HTML/JS widget to be able to execute a DB job, or execute some python code to render the result.
How I thought to achieve it
I understand this can be achieved to some degree using a combination of python and the `displayHTML()` to render the widgets in a cell's output.
A problem I faced
Because of the CORS policy enforcing 'allow-same-origin', and HTML iframe code being fetched from a 'databricksusercontent.com' url, the browser blocks the request (ie. my Azure Databricks API url is 'azuredatabricks.net').
What I'm looking for
To be able to make API calls from a notebook's iframe (using HTML/JS rendered with displayHTML()) without telling the browser application to ignore CORS policy enforcement when visiting my Databricks workspace website.

There are a few settings in the admin console of databricks, f.e. "Thirdparty iFraming prevention".
You might wanna look into that, but I am not sure if that would help you.
It might be better to look into something like PowerApps which then launches a notebook (using ADF f.e.).

Ah thank you
Yes, I see why you'd recommend PowerApps. Though, when my colleague tried them as a Desktop Application, they were limited to a phone-like view.
Anyway, thanks for pointing out the admin console option, I missed that one.
I tried it, though it doesn't seem to relieve the issue. Here are my iframe 'sandbox' attributes after disabling the Thirdparty iFrame prevention:
allow-scripts allow-popups allow-popups-to-escape-sandbox allow-forms allow-same-origin allow-downloads

I am dealing with a very similar issue attempting to embed the raiwidgets fairlearn dashboard into a workspace. The setting mentioned above has not had an impact and the dashboard still continues to spin due to the CORS error where the databricksusercontent.com content is attempting to retrieve from the azuredatabricks.net domain.

Bump - agreed. Doesn't work after changing the setting.
The attributes given to the iframe HTML tag that is to display the output don't change even with updating that setting.
Don't have too much web dev experience with CORS - this could be the wrong thing to point out.
