Should a woman cover her hands and face according to this hadith?

There is a hadith which says 'woman is awrah' , does that mean showing hands is haram? If i see people showing hands ,should i tell them about his hadith ? People might use other hadith to prove covering hands is not compulsory but they are not saheeh or clear. https://youtu.be/uESDtsbmZv4?t=12834 ;timestamp for the hadith used against covering hands etc What arguments are left for disproving niqab ? https://islam.stackexchange.com/questions/46640/how-reliable-is-the-hadith-the-woman-is-awrah/46645#46645 islamstackexchange How am i supposed to interpret this hadith.Can you provide evidences
