How to build a custom plugin to use inside the LAB?

[MNOP]

I want to prepare a custom plugin like this model fairness report inside the LAB. I want to display custom metrics and predictions as a view in in the LAB,while building the model in LAB I want to look at these metrics and visuals.
Where should I begin? Is there any resources available for the same?

Hi @MNOP ,
Note that this plugin is highly complex and customized and would best be handled with professional services.

We have some guides here for plugin creation in general but not for such custom webapp plugin that are available in models:

You can  of course try and install the plugin, convert to dev on an instance where the plugin is not being used, and start with that base for your custom plugin.
