Email event trigger

Hi,

I’m trying to intercept the event email sent for request received.
For example my vendor received an email about request received and I would like to send a message to him.
I tried to intercept the action:

function send_sms() {
	error_log('Event trigger when request received!!');
}
add_action('hivepress/v1/emails/request_received/send', 'send_sms');

but nothing was wrote on log, can I intercept this action? Or I am doing something wrong?

Regards

Thank you for waiting. Please try to change request_received to request_send in the hook name.
