FigJam toolbar in Safari: can't select Connectors

When I select the “Shapes and Connectors” button in the toolbar in FigJam in Safari, the second toolbar appears, but I cannot select any of the Connectors. All other items are selectable.

I discovered that on the main toolbar I can choose the Square, Ellipse, and Connector directly. But if I use this method to attempt to use a Connector, when the second toolbar appears, I cannot choose a different type of Connector.

This is:

• Safari Version 18.6 (20621.3.11.11.3)
• macOS 15.6 (24G84)

Closed and reopened Safari.

Tried it in a Private Window.

Works in Chrome...
