Carrot despite the people at the time calling her too irrelevant to join the crew especially in wano might unironically be too important to join the main crew

We know zou is the original location of a road poneglyph alongside fishman island and wano kuni
Both nations also being the location of ancient weapons/those who can use the voice of all things

Leading up to while there might not be an ancient weapon there there might be another sovereign

We know that the whales like the sea kings were also waiting for the return of their sovereign, carrot is only a year younger than shirahoshi, and that there’s deadass a whale tree in zou
So all points to the other sovereign being a mink from zou

As for why we’ve never seen her use that power
- She’s never met a whale and can likely only communicate with them same as shirahoshi with sea kings or momonosuke with zunesha
- Luffy hasn’t been able to use it until post timeskip

Look next to the whale and guess what it’s a mink. So yeah carrot like momonosuke and Shirahoshi might just be too important to join the crew. For better or worse it might also apply to Loki but idk
There’s a not zero chance that for better or worse Luffy gets another separate journey from the crew like post Sabaody to gather and team up with the reincarnations of nika’s and joyboy’s crews
