CRM do not support direct update of Entity Reference properties, Use Navigation properties instead. Error in creating quote based on opportunity.

I'm getting an error creating a quote based on an opportunity. I've shared the headers and request body I'm sending in Postman.

Request url: {organization_url}/api/data/v9.2/quotes

HTTP request method: POST

Headers:

'Content-Type': 'application/json; charset=utf-8',
'OData-MaxVersion': '4.0',
'OData-Version': '4.0',
Accept: 'application/json',
Authorization: 'Bearer' + {accesstoken}

Request Body (in Postman):

{

    "name": "OPP-0007514",

    "totalamount": 123,

    "_owningbusinessunit_value":"304*****-39a4-e***-a89b-00******ac12",

    "opportunityid@odata.bind": "/opportunities(a34*****-9abe-4***-9139-58*****7a747)"

}

Removing "_owningbusinessunit_value" key from the body gives an error: "The owner was not provided", So I've added that in the body.
