How can I have multiple tabs in a ubuntu terminal window for windows

I have a new laptop with Windows 10. I have installed Ubuntu terminal from Microsoft store.

I used to be able to get multiple tabs in the same ubuntu window and split windows in same tab as well.

Now I couldn't find the + button on the tab and there is no drop down menu too. Not sure what I need to do to enable them. It works well in my old Windows 10 laptop.

The only difference is in old laptop, I install WSL manually and in new laptop I installed ubuntu terminal via Microsoft Store.

Thanks.
