Upgraded to Utah changed the Close VA icon. How to get the X back?

[Lynda1]

When we moved to San Diego, I found a great article from Mark on how to change the close icon. We upgraded to Utah and it seems things have changed again.

This is what the icon looks like now for users to close the chat window.  How do I get this to an X again??

I have users asking VA how to close the chat window now.

This is the article @Mark Roethof wrote that was perfect. and now seems to ignore that snippet.

Hi there,

Are you using Agent Chat configuration or the legacy Service Portal Virtual Agent widget?

[Lynda1]

unfortunately, we use a custom portal that is in the works to using OOB esc portal.

When I go to esc portal the minimize icon looks like this

With the CSS code I used, after Utah upgrade, it looks like this

If you have any suggestions to get this either a minus sign or an X I would greatly appreciate it.

I am guessing we are using the Legacy VA? since we have had this for over 2 years. I would rather get this more to OOB so I do not have these issues with upgrades.

Oke is there any issue for you to start moving from legacy Service Portal widget to Agent Chat configuration (it doesn't matter if it's a custom portal or SP or EC)? Did you clone and edit the widget for example or is still the out-of-the-box widget, which is just legacy now?
Agent Chat configuration has more configurable options. Also replacing the icon is easier and robust.
