How to add Hebrew/Jewish recurring events to calendar?

in addition to the regular Gregorian calendar, I have the Hebrew calendar showing on the app.

But I can’t seem to find a way to add events the will recur every year according to their Hebrew date.

For example, my cousin celebrates his birthday on the Hebrew date and I want it to show on calendar every year without me having to add it manually every year.

How can I do that?

Thanks.
