Not a developer Id Certificate

HI I am trying to get a developer Id application but have not been successful so far.

I did get a certificate but when i verify it using the following

spctl -a -t install --context context:primary-signature -v TP_Sim_9_2_1c.dmg or this spctl -a -t open --context context:primary-signature -v TP_Sim_9_2_1c.dmg, it comes back as rejected and not a developer Id application certificate.

I tried to follow the instructions on following page, https://help.apple.com/developer-account/#/dev04fd06d56, but these instructions seem outdated since the screen shot does not match with actual loading page. Can you please share the correct instructions so that i can sign my app using this command codesign -v TP_Sim_9_2_1c.dmg. I intend to self-distribute my application.
