@learnfamily Welcome to FamilySearch.
Your living daughter and yourself currently have separate/private Living Space. For your daughter to link to your tree - she can input separate living placeholders for you and any living grandparents (your parents) - and then attach those profiles to their deceased ancestors (great-grandparents /your grandparents).
If you mean how does she link your account to a Family Group - consult the Help Center articles:
Someone will need to be the Family Group Administrator, create the group and send invitations to other family members to join the Family Group.0
