I have successfully implemented the SSO using Oauth2 and "Log in with Google" button is dosplayed on log in page. On log in page for users I only want to show the "Log in with Google" button and hide log in form. A solution like given in this post https://moodle.org/mod/forum/discuss.php?d=261950 . But, in moodle 3.2 moodle/login/index_form.html has been removed.
How can I customize my page at https://imdcollege.edu.pk/lmstest/login/index.php to only show the "Log in with Google" button or alternatively use a custom log in page and keep this page for admin access only.
