Hi all, I'm trying to inherit model product.product.form 
I got some custom fields on product.template and would like to show them on product form that opens up when product name is clicked on sales order. 

Tried to do it like this https://ibb.co/xXqH7rp but got error saying: 
"Model not found: product.product.form"

Here is short gif I recorded just to show you how to get to this view https://recordit.co/Jc8I0Och8p

Does it have something to do with the fact that it's inherited view? Thank you!
