Why Formik handleBlur doesn't run two functions?

Question

After user types the name, I check for its uniqueness in handleBlur. The check runs fine, but the warnings from yup are not showing on blur. Thus handleBlur('name') is not running:

// onBlur={handleBlur('name')} // This runs fine! 

 onBlur={async () => {
   const isUnique = await checkUserNameUniqueness(values.name);
         if (!isUnique) userNameIsNotUnique();
         handleBlur('name');
}}
                        

I tried to run it without sync/await but nothing.
Is there a way to fix that?

As I see here there is a way to run two functions in onChange
