Is it permissible for a woman to teach men and women Tajweed of the Holy Quran via PalTalk?

There is no religious impediment to a Muslim woman teaching others or learning the Tajweed of the Qur’an and beneficial sciences, whether directly or through communication channels, provided that it adheres to the Shariah regulations. The Mothers of the Believers and the female Companions used to teach people goodness, in compliance with the words of Allah Almighty: "And remember what is recited in your houses of the verses of Allah and the wisdom."
