Hi @haamid Welcome to the Zoom Community! We are happy to have you here 🙂

To add or change your virtual background during a meeting, click on the upward arrow (^) next to Start/Stop Video. Click Choose Virtual Background, and select any of your backgrounds. If you do not have this option, let us know and add a screenshot if possible. Thank you!
