No Approval Messages

I have enabled the option of Approval in status – https://prnt.sc/p1c63g but still, I am not getting any messages ( I am sending the message as guest not admin ) and also in the guest post there is no message which says that his/her message is in approval.

Will you please help me to find the path exactly from where I should approve the topic.
