Accidentally delete package, how to get the list of those deleted pacakges

Hello, I was trying to delete and re-install the cups related packages as the print is not working. However, many unrelated packages, such as firefor,
thunderbird, are getting un-installed and Yast didn’t warn me about it. The process is aborted.

However, the Yast GUI is now in white color, and does’t looks as good as before.

I am trying to re-installed all the accedently deleted packages, is there a way to list the recent changes? Many thanks!

In YaST Software check > Extras > Show History > and scroll down to see the latest changes.

Thanks, I found it under the /var/log/zypp as well.

Are you absolutely certain?
