Send email by Interactive Report in Oracle Apex

I already set configuration of SMTP and I could send an email by the PL/SQL Code as below successfully,

Declare
l_body clob;
l_body_html clob;
begin
l_body := 'To view the content of this message, please use an HTML enabled mail client.' || utl_tcp.crlf;

apex_mail.send (
p_to => 'abc@gmail.com',
p_from => 'abc@gmail.comm',
p_body => 'This is a test email',
-- p_body_html => l_body_html,
p_subj => 'test' );

apex_mail.push_queue();
end;

But when I try to send an email from Interactive Report (Actions->Download->Email) is not working???

Please advise,

Thanks
