If you want to delete the chat content, [open the chat dropdown menu](/peertube-plugin-livechat/documentation/user/viewers), then click on "Destroy".A popup will open, asking a confirmation.
The chat will be automatically recreated each time someone tries to join it as long as the video exists, and has the "{{% livechat_label use_chat %}}" feature activated.
You can fill several "{{% livechat_label livechat_configuration_channel_forbidden_words_label %}}" fields.When a user sends a message that match the configured criteria, the message will automatically be deleted.
