Чтение и запись электронной почты с помощью Microsoft Graph API Java. ⇐ JAVA

[Anonymous]

Я хочу читать и отправлять электронную почту с помощью Microsoft Graph API. Я пробовал использовать DeviceCodeCredentials, и он работает нормально, но я хочу читать электронные письма без какого-либо взаимодействия с пользователем на серверной стороне. Используя DeviceCodeCredentials, он просит меня войти в систему, используя мой адрес электронной почты, и ввести предоставленный код.
Ниже приведен код, который я написал с ClientSecretCredentials, который выдает мне ошибку ниже.
