Yes, the first paragraph,"A sapphic person... is a woman, or woman-aligned person who is attracted to other women or woman-aligned people." You can totaly use the term saphic if you like thogh i would encourage you to continue exploring other sexual identities depending on what genders you are attracted to as a bixexual becuse there are identites that cover non binarys that are attracted to more that one gender though i am not able to list any off due to not having them memorised sorry.
hope tis helps from a nibling (non-binary sibling)
