@mentions not working in comment

I am trying to mention the user when replying to their comment on my page post. I am using the following endpoint https://graph.facebook.com/v19.0/136580295900502_2467377823447413/comments?access_token= req body: { "message" :" hello @[7132049906831253] test v19 from postman. " }
but in the reply comment posted on facebook, the PSID is replaced by the name of the user but it is not clickable.
