Error in users field for AuthorizationGroups model validation

[chinchy]

Describe the bug
Pydantic model AuthorizationGroups has incorrect validation for the users field.
This field has the following type annotation: users: Optional[Dict[str, StrictStr]] = None. However, the validation processes the field value like a string.

To Reproduce
Short script for reproduction:

from fireblocks.models import AuthorizationGroups

auth_group = {"th": 1, "users": {"00000000-0000-0000-0000-000000000000": "NA"}}

AuthorizationGroups.from_dict(auth_group)

Expected behavior
Dict data was validated, and the model object was created.

Actual Behavior

Traceback (most recent call last):
  File "<input>", line 5, in <module>
  File "/Users/user1/Library/Caches/pypoetry/virtualenvs/test-TTiCIVEu-py3.12/lib/python3.12/site-packages/fireblocks/models/authorization_groups.py", line 94, in from_dict
