+    Set AAK groups based on AAK claims. AAK groups need to be parsed from a collection of AAK claims,
+    so we cannot rely on Open WebUI's claims mapping. Parses the relevant AAK claims and adds them
+    to the "groups" list. This enables us to rely on Open WebUI's role management for user role assignment.
+
+    To ensure unique group names, they are constructed as "<aak_department_name> (<aak_department_id>)".
+
+    Example claims:
+
+    "companyname": [
+        "Aarhus Kommune"
+    ],
+    "division": [
+        "Kultur og Borgerservice"
+    ],
+    "department": [
+        "Borgerservice og Biblioteker"
+    ],
+    "extensionAttribute12": [
+        "ITK"
+    ],
+    "Office": [
+        "ITK Development"
+    ],
+    "extensionAttribute7": [
+        "1001;1004;1012;1103;6530"
+    ]
+
+    The ID's for the departments are given sequentially in "extensionAttribute7". Users in management postitions will
+    not have five levels of AAK groups. This will show in the length of "extensionAttribute7" but will not show in the
+    other claims. In the above example a manager will still have the "Office" claim, but it will repeat the value from
+    "extensionAttribute12" and "extensionAttribute7 will only contain "1001;1004;1012;1103"
+
+    Note: ENABLE_OAUTH_GROUP_MANAGEMENT and ENABLE_OAUTH_GROUP_CREATION must be set to 'true'

+        user_data (dict): The decoded OIDC token
+
+    Returns:
+        The decoded OIDC token with the AAK group names added to the "groups" list.
