* fix: add name property to delegation credentials for type compatibility The MultiDisconnectIntegration component expects credentials with user.name property, but delegation credentials only had user.email. This caused a type mismatch when spreading both credential types together in appCredentialsByType handler. Added name: null to the delegation credentials user object to ensure type compatibility.

Now we check if name has a truthy value before using it. Also fixed lint warning by using optional chaining for onSuccess callback. Co-Authored-By: Volnei Munhoz <volnei.munhoz@gmail.com> * fix: add explicit return type and typeof checks to getUserDisplayName The function now has an explicit return type of string | null and uses typeof checks to ensure proper type narrowing. This prevents TypeScript from inferring a wider return type that includes {} when the user object has properties with non-string types.
