What are the conditions for an online Urfi marriage between a young man and a young woman in two different countries, what is the ruling on each of them seeing the awrah of the other via video, and is the presence of witnesses a condition for this marriage?

You must repent of the forbidden relationship between a man and a foreign woman, as this relationship leads to corruption and indecencies, as happened between you with the viewing of bodies. It is not permissible for you except through a legitimate marriage that fulfills the conditions of validity, namely offer and acceptance, a guardian, and witnesses. The verbal agreement between you is not a legitimate marriage. If a legitimate marriage does not occur, then this relationship must be severed immediately. Inability to stay away from it is a temptation from Satan. Moreover, this acquaintance leads to defiling one's honor and a bad reputation. It is worth noting that many marriages that occur through online acquaintance end in failure.
