Looking for an adjective for an elected but not yet in charge person

I’m looking for an adjective for an elected but not yet in charge person.
I remember that there was a synonym for “soon to be” and “President-elect” but that’s not the word I’m looking for. As far as I remember it started with in[...] and it could be used with ... president.
I already did an extensive Google search and also here on StackExchange, but I can’t find the appropriate word.

Answer

The word I was looking for was designate (Cambridge Dictionary), the in... was a mislead, sorry.
