add trendlines in Plotly.js

Looking through the documentation of Plotly I came across the trend line possibilities in Plotly.py: https://plotly.com/python/linear-fits/
I'm searching for a feature within Plotly.js to draw a trend line/regression line/fitting within a scattered graph. Though it looks like this feature is not available in the JavaScript version of Plotly.

The requests for such a feature have already been there within the community for some time but the answer was to generate it elsewhere. I am using Plotly within Mendix and using other libraries to create something for Plotly is not really a well maintainable solution there.

Would it be a possibility to add trend lines as a feature within Plotly.js?
Something like this would be great as an example:
https://developers.google.com/chart/interactive/docs/gallery/trendlines

Start by reviewing the Plotly.py linear-fits documentation and the linked Plotly community discussions, then compare the Google Charts trendlines example. The issue names no Plotly.js files or tests; scope would need to be defined for a supported trendline or regression feature in scatter plots, including how completion would be verified.
