Modern Content Editor Web Part
The Modern Content Editor Web Part replicates the classic SharePoint Content Editor Web part and lets you link to a HTML file containing HTML / JS or insert HTML code directly into the page. This solution is licensed under the MIT license (free to download and use).

The webpart has been updated to make it compatible with the new CSP policy that Microsoft starts enforcing on March 1, 2026. It reads the HTML loaded with the Content link or inline in the HTML code section and extracts the script tags. It then loads the external scripts by creating script tags and adding them to the page DOM. Inline scripts will be executed using the function constructor to comply with the CSP rules.
Please note that loading external scripts from outside of the current site collection requires that the script source is whitelisted in the tenant under trusted script locations.
I have also added a title property on the webpart that can be used to describe what the code does for easy maintenance on a page with multiple webparts.
