How can I deploy a fine-tuned GPT model in Azure via Python without using a token (e.g., using an endpoint key instead)?

I follow Azure's tutorial on fine-tuning GPT. Here is the code for the deployment phase:

# Deploy fine-tuned model

import json
import requests

token = '[redacted]'
subscription = '[redacted]'
resource_group = "[redacted]"
resource_name = "[redacted]"
model_deployment_name = "gpt-4o-mini-2024-07-18-ft" # Custom deployment name you chose for your fine-tuning model

deploy_params = {'api-version': "2023-05-01"}
deploy_headers = {'Authorization': 'Bearer {}'.format(token), 'Content-Type': 'application/json'}

deploy_data = {
    "sku": {"name": "standard", "capacity": 1},
    "properties": {
        "model": {
            "format": "OpenAI",
            "name": "gpt-4o-mini-2024-07-18.ft-[redacted]", #retrieve this value from the previous call, it will look like gpt-4o-mini-2024-07-18.ft-[redacted]
            "version": "1"
        }
    }
}
deploy_data = json.dumps(deploy_data)

request_url = f'https://management.azure.com/subscriptions/{subscription}/resourceGroups/{resource_group}/providers/Microsoft.CognitiveServices/accounts/{resource_name}/deployments/{model_deployment_name}'

print('Creating a new deployment...')

r = requests.put(request_url, params=deploy_params, headers=deploy_headers, data=deploy_data)

print(r)
print(r.reason)
print(r.json())

That works fine, but the token generated via az account get-access-token expires quickly. Looking at the documentation:

az account get-access-token [--name]
                            [--resource]
                            [--resource-type {aad-graph, arm, batch, data-lake, media, ms-graph, oss-rdbms}]
                            [--scope]
                            [--tenant]

there are no parameters to extend the token lifespan.

This annoys me. How can I deploy a fine-tuned GPT model in Azure via Python without using a token (e.g., using an endpoint key instead)?
