**Description**  
For Chrome, we are using single canvas to render videos for all the participants. But multiple rendering is not supported in Firefox and Safari browsers. Is there a sample code which uses single canvas per participant as a fallback for these browsers?

**Which Web Video SDK version?**  
1.1.7

**Device (please complete the following information):**

- Device: Macbook
- OS: Monterey
- Browser: Chrome
- Browser Version: 99.0
