Hi, problem update with change splash and icon

Hello, we have updated our icon and splash of our application, but for the production versions these have not been updated, we have been reading Publishing updates - Expo Documentation
but it does not specify the procedure to follow.

Does anyone know what is the procedure to follow or the commands used so that these changes are reflected?

Have you made a new build using expo build:ios and expo build:android? You must create new builds and upload to the respective app stores or add them to your devices.
