Error in Deepl automatic translation

Hi, since recently we are receiving this error message for our automatic translation via Deepl:

{“message”:”Legacy authentication method ‘form body’ is no longer supported. Please update to header-based authentication. Find more details in our docs: https://developers.deepl.com/docs/resources/breaking-changes-change-notices/november-2025-deprecation-of-legacy-auth-methods. You can find more info in our docs: https://developers.deepl.com/docs/getting-started/auth”}

How do we fix this? Is it a known issue?

We are on TranslatePress Version 3.0.7
