* Calling other characters: You can call your friends, rivals, and other important characters to get information or trigger events.
* Checking your Pokémon's status: You can view your team's stats, moves, and items.
* Checking the map: You can see your current location and navigate to different areas.
* Receiving news: You can receive news updates on various events happening in the game world.
* Using certain applications: Some games feature additional applications within the Pokégear, such as a Pokédex, a Trainer Card viewer, or a Dowsing Machine.
Instead of registering Gym Leaders, you can find them at their respective Gyms:
* Each Gym Leader is stationed at a specific Gym in the region you are exploring.
* To challenge a Gym Leader, you need to defeat all the trainers within the Gym first.
* Once you have defeated the Gym Leader, you will receive a Badge, which allows you to progress further in the game.
Therefore, you won't find an option to register Gym Leaders in your Pokégear. You need to locate them at their Gyms and challenge them for a badge.
