How create national team in FM 24

Hello, how create national team in FM 24? I mean how unlock the continent.

I want to add the Marshall Islands to Oceania, in the older games there was a way to enable the "Continent"

 Thank you!

here's a video how you have to do it. its also working the same in fm 24, but if you add the continent to it there may be some issues and the nation is not taking part at the qualifiers for the regional national tournaments, world cup qualfiers are usually no problem.
