I imported the CASHU SDK into the project through cocopods and found that I could use the CASHUConfigurations class, but could not find its properties. How can we solve this problem
`@import CASHU;

        CASHUConfigurations *config = [[CASHUConfigurations alloc] init];
       // XCode prompts that the clientID attribute cannot be found
        config.clientID = "XXXXXX"

`
