Hi,
Can I ask if Helix template login 'responds to the onUserLoginButtons' in Joomla4!
Thanks

"As noted, our code DOES NOT render the login buttons in Joomla 4. Our code simply responds to the onUserLoginButtons event which was added in Joomla 4. Plugins responding to this event convey all the information Joomla needs to render additional login buttons such as WebAuthn (included in Joomla), SocialLogin etc.
If your extension does not render these buttons please talk to its developer. They need to update its code for Joomla 4. There is nothing you can do with an override."
