In this code below, Which folder can I get the pop up error message that shows if user enters an amount below minimum

I need to edit the error that shows if a user enters an amount below minimum but I can't find the file to edit the pop up error response that shows if amount I less than withdrawal limit.

Here is the code.

<div class="row">
    <div class="col-md-9">

        <div class="card">
            <div class="card-header">
                <h4 class="card-title">withdrawal -
                    <small class="category">Cash Out Fund.</small>
                </h4>
            </div>
            <div class="card-content">
                <div class="row">
                    <div class="col-md-2">

                                    </div>

I need to edit all error response that pop up in the file and any other error response in the entire website.
