WSO2 IS - Enable Mobile Number Verification when number is updated - wso2

Question

We are trying to use the Mobile Number verification on Mobile number update with WSO2 Identity Server (v5.11.0) as per this guide, while the SMS OTP is being sent, it is being sent to the old mobile number.
Example:
User with mobile number 111111
We are sending the request to the SCIM2.0 API https://hostname/scim2/Me to update the mobile number with the following request:
{
"schemas":[
"urn:ietf:params:scim:api:messages:2.0:PatchOp"
],
"Operations":[
{
"op":"replace",
"value":{
"phoneNumbers":[
{
"type":"mobile",
"value":"222222"
}
],
"urn:ietf:params:scim:schemas:extension:enterprise:2.0:User":{
"verifyMobile":true
}
}
}
]
}
The SMS OTP is being sent to the old mobile number (111111) instead of the new one (222222)
The guide clearly states:
When a user updates their mobile number in the user profile, an SMS OTP is sent to the new mobile number.
Is there another way to configure that functionality, are we missing a step ? or should the request be modified for us to have the correct behavior?
PS: The server is configured as per the guide

Looks like in the sample event publisher, the number to which the SMS is sent is defined as "to"={{mobile}}. This will pick the existing mobile number persisted under the claim http://wso2.org/claims/mobile. Change that value as to"={{send-to}}. Then it will send the SMS to the verification pending mobile number. The updated sample event publisher should be as follows.
<?xml version="1.0" encoding="UTF-8"?>
<eventPublisher name="HTTPOutputEventAdapter" processing="enable"
statistics="disable" trace="disable" xmlns="http://wso2.org/carbon/eventpublisher">
<from streamName="id_gov_sms_notify_stream" version="1.0.0"/>
<mapping customMapping="enable" type="json">
<inline>{"api_key"="xxxxxx",
"api_secret"="xxxxxxxx",
"from"="NEXMO",
"to"={{send-to}},
"text"={{body}}
}</inline>
</mapping>
<to eventAdapterType="http">
<property name="http.client.method">httpPost</property>
<property name="http.url">https://rest.nexmo.com/sms/json</property>
</to>
</eventPublisher>
