How to translate hover text on " check conflicts"

[Samyukta1]

I want to translate hiver text on check conflicts which is coming from a "ui macro" - "change_request_conflict_progress".

The "check conflict" button is displayed from line 101.

<button style="white-space: nowrap" class="btn btn-default" id="conflict_action_run">$[gs.getMessage("Check Conflicts")]</button>

But Im not getting from where is the hover message coming from? Can someone please help me.

I suspect it is coming from "class or id" in the <button> tag but not sure how to check that
