Welcome email not getting triggered for users created using SCIM REST API

Hello,

We have observed a strange behavior while creating an user using SCIM REST API, even with a valid email id and notification enabled, the welcome email doesn't get triggered. However, if we create the user manually with same email, welcome email triggers instantly.

Payload we are using:

=================

POST: https://eee-dev2.fa.ocs.oraclecloud.com/hcmRestApi/scim/Users

{
"schemas": [
"urn:scim:schemas:core:2.0:User"
],
"name": {
"familyName": "TEST4",
"givenName": "HR M"
},
"active": true,
"userName": "HR.M.TEST4",
"emails": [
{
"primary": true,
"value": "Raktim.Pal@ccc.com",
"type": "W"
}
],
"displayName": "James M Bond",
"password": "Welcome1"
}

FYI - All notifications are enabled. We have also run: ESS process - Send User Name & Password E-mail Notification still no luck.
