Bubble, theme, where is the bubble that is not in expression?

1. To set bubbles, click Settings to enter the setting window, then click bubbles, themes and expressions on the setting window to enter the bubble, theme and expression setting window, and then click colorful bubbles to enter the colorful bubble setting window.

2. After entering the colorful bubble setting window, I saw many beautiful bubbles, some of which are free and some need to be opened for VIP members. If they are not members, you can click to select a free bubble. When a bubble is selected, a tick will be placed in the lower right corner of the bubble, indicating that the bubble is set to be currently used.
