@Esox76 ,
Well, actually is a two actions process.
First of all you need to get the options from Data Verse choice options. For this you have to use a Invoke a HTTP request action:

Identify your dynamics domain ... The simplest way is to go to powerapps admin center -> open the environment and copy the first part of the address (something like https:\\...dynamics.com\)
and the internal name of your ChoiceOption ... go to make.powerapps.com ->DataVerse -> ChoiceOptions and get the name value (not display name).
Then to create a choice value inside a create Data Verse row action:
/InternalNameofTablePluralName(ID)
- where ID will be taken from the first action based on your needs.
