To have your webinar visible on your channel, you can follow the steps:
Click on your webinar.
Click on 'Edit webinar'.
Navigate to 'Registration' > 'Settings'.
Scroll down to 'Show webinar on Channel'.
Flip the switch.
If you do not want to add the webinar to your Channel, you can decide to hide it from the Channel by using the switch. This option is enabled by default when you create a public webinar. The option is disabled by default when you create an unlisted or private webinar. You can find more about the access settings here. After creating the webinar, you can still change this setting using the switch.
Please note! This switch is disabled if you have multiple channels. When using multiple channels, you can only add or remove webinars through the channel editor.
