Activity for Train extractors scope

Hi I am doing a project for a customer on document processing and my process is using ML extractor and it works without any issue.

Now I want to add “train ML extractor” scope. Can you please help me to locate one activity which I can add to train ML extractor scope ?

I have gone through this link but did not follow much.

Can you please help ?

Thanks in advance,

Hey @viswanarahari ,
I am also going through these topics nowadays.
So to get Train ML extractor you have to add package of it.
plus the link you are following is not relatable. Its of Custom activities and you are using Uipath trainer.
