What does a bubble notification look like, HarmonyOS?

1. The developer option-bubble notification switch is turned on;

2. set-notification-notification management-corresponding application bubble notification is turned on, and non-silent notification is set in the corresponding notification category and bubble notification is turned on;

3. adapt the bubble notification effect when sending notification.

if both 1 and 2 are turned on, no bubble will be displayed when the notification message is received, indicating that the application has not adapted to the bubble notification effect yet. 4. Effect expectation: The effect is similar to a suspended window. Expanding is a small application window, and closing is a side suspension ring that looks like a bubble.
