How to get value of Sku Id of Office 365 license Python

By using msal in Python to create a token, I'm attempting to assign a license to the user.

import msal

client_id = xxx
client_secret= xxx
tenant_id = xxx
authority = f"https://login.microsoftonline.com/{tenant_id}"
scopes = ['https://graph.microsoft.com/.default']

app = msal.ConfidentialClientApplication(client_id, client_secret, authority=authority)

result = app.acquire_token_for_client(scopes)
access_token = result['access_token']
print(access_token)

Where can I find license SKU Id? Nowhere in Portal can I find it. Or is there a way to get it from graph call or powershell?

Once I have the SkuId, I want to assign that license to the user. This is the license assignment document that I've managed to obtain so far, but lost at SkuId part:

To get the value of SKU IDs of Office 365 licenses, you can make use of below Graph API call:

GET https://graph.microsoft.com/v1.0/subscribedSkus?$select=skuPartNumber,skuId

I registered one Azure AD application and granted API permissions:

I used below python code to get access token and print SKU IDs of existing licenses in organization:

import msal
import requests

client_id = "appID"
client_secret= "secret"
tenant_id = "tenantID"
authority = f"https://login.microsoftonline.com/{tenant_id}"
scopes = ['https://graph.microsoft.com/.default']

app = msal.ConfidentialClientApplication(client_id, client_secret, authority=authority)

result = app.acquire_token_for_client(scopes)
access_token = result['access_token']
print(access_token)

url = "https://graph.microsoft.com/v1.0/subscribedSkus?$select=skuPartNumber,skuId"
headers = {
    "Authorization": "Bearer " + access_token
}

response = requests.get(url, headers=headers)
data = response.json()

for sku in data['value']:
    print("\nSKU Part Number:", sku['skuPartNumber'])
    print("SKU ID:", sku['skuId'])
    print()

Response:

You can assign license to user with below python code by adding few lines:

import msal
import requests

client_id = "appID"
client_secret= "secret"
tenant_id = "tenantID"
authority = f"https://login.microsoftonline.com/{tenant_id}"
scopes = ['https://graph.microsoft.com/.default']

app = msal.ConfidentialClientApplication(client_id, client_secret, authority=authority)

result = app.acquire_token_for_client(scopes)
access_token = result['access_token']
print(access_token)

url = "https://graph.microsoft.com/v1.0/users/xxxxxxxxx/assignLicense"
headers = {
    "Authorization": "Bearer " + access_token,
    "Content-type": "application/json"
}

payload = {
    "addLicenses": [
        {
            "skuId": "c7df2760-2c81-4ef7-b578-5b5392b571df"
        }
    ],
    "removeLicenses": []
}

response = requests.post(url, headers=headers, json=payload)
print(response.status_code)
print(response.json())

Response:

To confirm that, I checked the same in Portal where Office 365 E5 license assigned successfully to user:
