I have a function which makes a GET request and returns a string of HTML content looking like this:

<div class="mx_Parent">
    <a href="" target="_blank" rel="noopener">
        <img src="themes/img/logos/logo-letter.png" alt="" class="mx_Logo"/>
    </a>
    <h1 class="mx_Header_title">_t("Welcome to Test")</h1>
    <div class="mx_ButtonGroup">
        <div class="mx_ButtonRow">
            <a href="#/login" class="mx_ButtonParent mx_ButtonSignIn mx_Button_iconSignIn">
                <div class="mx_ButtonLabel">_t("Sign In")</div>
            </a>
            <a href="#/register" class="mx_ButtonParent mx_ButtonCreateAccount mx_Button_iconCreateAccount">
                <div class="mx_ButtonLabel">_t("Create Account")</div>
            </a>
        </div>
    </div>
</div>

This content is then rendered by React, however, I need to somehow delete this part:

<a href="#/register" class="mx_ButtonParent mx_ButtonCreateAccount mx_Button_iconCreateAccount">
    <div class="mx_ButtonLabel">_t("Create Account")</div>
</a>

I'm not exactly sure how would I edit this since it's just a big string. Maybe using .replace() ?
