You can copy the bullet point symbol from HERE, and paste it in the text element, or, if you use Windows, simply press ALT+7 on your keyboard.
As a workaround, you could use a dash or some other symbol in the text element to create a list.
Pro tip: You can also copy-paste any symbol from any text editor/symbol database. For example, if you want to copy an emoji, simply copy your desired symbol and paste it to your website's text element.
