New tab open in another browser

Our automation script runs on Chrome browser. Click on a button in the application opens a new tab, but it opens in IE browser.
I use SwitchToWindowIndex() in the script and it doesn’t work. Glad anyone can help on this.

Thanks !

Isn’t it that you need to select Chrome as your “default” browser?
