fail to acquire embed cookieless session with not found 404 response

[huhuhong]

i have make sure

-   user credentials (client-id/secret) have the full admin permission in looker platform
- embed domain url added

example curl as below

curl --location 'https://xxx.looker.com/api/4.0/acquire_embed_cookieless_session' \
--header 'Authorization: Bearer xxx' \
--header 'Content-Type: application/json' \
--data '{
"external_user_id": "123",
"external_group_id": "999",
"first_name": "user",
"last_name": "name",
"session_length": 3600,
"force_logout_login": true,
"permissions": [
"access_data",
"see_lookml_dashboards",
"see_looks",
"download_without_lim"],
"models": ["sandbox_bigquery_asset"]
}

May i know what other looker platform setting i need to enable ?
