@Darwiin You can configure the chatbot itself to only display when a team member is available, article here.
'Availability
Decide when the chat widget should appear on your site depending on your team’s availability set in your channel settings. Click the Availability dropdown menu and select an option:
Only show when team members are available to chat: the chat widget will only appear during business hours or when at least one team member is available.'
Hey! thanks for the answer. I know that but I want that the chatbot is always available because even when I don't have an agent available it remains useful for my users. I just wanted to know if I could change this green icon which in my particular case of use does not make sense
