# Player — Request Visual Viewport

In certain situations, the LiSA Player sends a message to request the visual viewport from the host app or environment. This typically occurs during UI transitions, such as entering floating player mode or when the virtual keyboard appears.

This message is sent by the LiSA Player to the host app / environment.

### Properties
