Custom tab in task Details Tabs

Hi community!
Where can I find guide/how to about tasklist.task.detail plugin implementation to add it like on screen below?


Have a look at below docs


Hi @hassang ! Thanks for your answer.
Yes, I saw this doc, there are only 2 links to small code examples in the end backend frontend

and i was hoping that somebody created small but detailed guide (like how to fro creating plugin for cockpit) with steps to reproduce description (how to build plugin, where to place it, how to hook up plugin for tasklist) but I can’t find such tutorial
