How can i share the light group to my friends ?

I group 4 for light together , but i can’t find the sharing option on the light group button, i try to share four of light bulb to my friend by each , but i can’t group together with another phone ?

You can only share single bulbs, they have to group them…

but how should I create automatization workflows to be used by my whole familly, when several lamps contain several bulbs and I want to define all this logic in one place?
I could define the automatization only one time in my account. But how other users can also control these groups using their app or their Google Assistent? Or should I do this in third party solutions outside yeelight / MI Home ecosystem?
