Speech bubble steps consist of a speech bubble anchored to the corner of the browser window. They may sometimes be in the way of the content users are expected to interact with. Usually, when this is the case, I’d recommend using a Tooltip step instead, which places the tooltip outside of the interaction content.
If you must use a speech bubble step, your users can now minimize the speech bubble by clicking the avatar. Clicking it a second time will restore the bubble again. If a trigger causes Userflow to go to the next step, the speech bubble will automatically be restored, too.
