Logout Issue in wordpress website login usingAUth0 plugin

I’m having an issue when logging out of my WP site with Auth0, when I click on the logout button/link I get redirected to the homepage with a number next to it [mywebsiteurl/?1639428053], I guess it could be the nonce(?)
but the user remains logged in.
Reading through the topics I have found that the federated option no longer works, can someone point me in the right direction in how to achieve a successful logout?
Also I don’t know which setting is required for logout in auth0 dashboard.
please help if any one know the solution.
Thanks in advance!
