Answer by Layan Jwei)If you would like to try it and see if it's related to this property, you can create a new menu item for one of the forms, make this property as true and see if the button starts appearing.
Additional questions ) I didn't understand the part above. Are you saying it can be solved? If a solution is possible, how do we know it is possible?
As I mentioned in my first reply, those forms are designed to have these properties as false. However, when I looked at the difference to see why SalesTable form has this "Get link" while other forms don't, I noticed this "Allow root navigation property", and it seems it's set to false in the menu items for the forms you mentioned. So what I wanted to say is, it might be because of this property.
And yes, if you create an extension of the menu item, this property will be disabled, you can't change it. However, If you would like to try it and see if it's related to this property, you can create a new menu item for one of the forms, make this property as true and see if the button starts appearing.

You got some replies already, but can you tell me what you mean by "Get a link be activated in the screen below"? I don't know what exact link you are referring to. I can only see 4 screenshots without further explanation.
