Divorce of expats while the husband is outside the UAE

I am from the Philippines, married to an Egyptian. We were both in Dubai, however, my husband went back to his home country in 2018 and we did not see each other since.

We were in constant communication but the distance took its toll on our relationship and he recently said that he wants to get married again in Egypt.

He knew that if that happens, we need to dissolve our union. We do not have kids, property, or bank accounts. Where can I file for divorce in Dubai?

Thank you!
