There are a few ways to hide chat on BIGO. You can use the built-in chat feature, or you can use a third-party chat client. The built-in chat feature is the best way to hide chat on BIGO. To use the built-in chat feature, open BIGO and click on the three lines in the top left corner of the screen. Then, select “Chat.” If you use a third-party chat client, you need to be careful about how you choose one. Some clients are more secure than others. You should also be sure that the client will work with BIGO’s security features.
