How to make a such user object Like this?

this component is Taco,for robot.
but i find somethin interesting:
most component of Taco is a UserObject,but you cannot open it by double click it,or it cannot have place to input password to open it, it acts like a “gha” component.
Can someone know how to do that component?
Thank you very much!

Taco Link in food4rhino:

A compiled (like .gha) single component can be wrapped into a user object
Not sure why the creator wanted to have this redundancy but it could be for easier organization of tabs

Why do you think it is a userobject? There is only one gha file in the link…
