Axon Social Login facebooks oauth redirect page is not exist

[fenixlam]

Prestashop version is 1.7.8.0. I have installed Axon Soical Login plugin. It has Facebook OAuth support. So I want to use its OAuth login for the client login. I enabled it and filled in the Facebook ID and Secret, it shows up https://[www.domain.com]/module/nrtsociallogin/facebook as OAuth redirect link. I pasted it into Facebook OAuth redirect URL setting and check the URL, return failed. So I pasted it into browser, return 404.

Obviously, the error is caused by OAuth redirect page does not exist! How to fix it?
