Need to change placeholder of search field on the Moveworks assistance

I need to change the placeholder text displayed in the search field of the Moveworks Assistant.

Currently, the text appears as:
“Find answers, automate tasks, or create content instantly.”

I would like to update this placeholder text.

Could you please confirm whether this change is configurable? If so, kindly provide the steps or location within the Moveworks setup where this modification can be made.
