[Feature Request] Update the copy button status when it's activated.

[dataCenter430]

Motivation

In the current codebase there is no feedback when copying chat messages.
The copy button:

• does not show a toast/popup
• does not change to a check icon after copying

Solution

Could we implement the feature right away?

Alternatives

No response

Additional context

Closes #1259
