I don't think Chrome on iOS supports web Bluetooth either, you need to use the desktop version. Also I believe the Bangle js can only be connected to one device at a time, so try to disconnect it from the WebBLE app.
I’ve tried to disconnect before, and when I do the watch disappears from the list of connected devices on my phone’s Bluetooth listing. Is there changes I can make in my iPhones Bluetooth to make sure it can see the watch? Seems like it only can through that WebBLE app.
