How do I hide the sticky avatar until the bot has started?

You can make the bot not show the sticky avatar until it’s started with the following code that needs to be added to your HTML page:

<script
    type="text/javascript"
    src="https://quriobot.com/qb/widget/3MY12wr8gmd8AROG/NvRW9mA761E3BgZ4?showStickyAvatar=closed">
</script>

Note the showStickyAvatar parameter in the code snippet above, which you can set manually to closed
