Good to know before you add it
The widget does not read your Notion databases. You type the list into the widget itself by tapping the list button (“8 Names” at first), and it stays in your browser. A teammate who opens the same page sees the sample list, not yours, so for a draw in a meeting, one person spins and shares the screen.
The widget keeps the color this page has at the moment you copy the link. If you work in dark mode, pick a dark color with the palette at the bottom right before tapping Link for Notion, and the block will blend into your page. The width follows the block; if the wheel looks cut off, drag the edges of the block to make it bigger.
