How can I change the default charset globally?

[Ric Ric]

Hello,

I am using MySQL Workbench for Mac, version 8.0.18.
My database uses AWS Aurora and uses utf8mb4 (because I want emojis)

However, when I press "Synchronize Model with Database", the script has
ALTER SCHEMA `mydb` DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
And
DEFAULT CHARACTER SET = utf8;
for every single table.

I know that I can change that manually for every single table, but that is very annoying.

How can I change that so the entire model uses utf8mb4? I don't see anything in the menus or preferences.

Thanks a lot.
