Angular reactive from getting “Cross-Site Request Forgery” issue in the fortify scan

in angular application we are using the reactive form and formGroup,its working fine but when i run the fortify scan we are getting the issue like

    "The form post at xxxx.component.html line 4 must contain a user-specific
 secret in order to prevent an attacker from making unauthorized requests."

.html

<div class="row no-gutters">
    <div class="col diagonal center">
        <form [formGroup]="searchForm">
            <div class="row ldes-mg m-1">
               // form controls here 
              // form controls here 
            </div>
        </form>
    </div>
</div>

issue shown on <form [formGroup]="searchForm">

there are some article which suggest to implement “Backend CSRF Token Setup: Make sure your backend framework is set up to provide a CSRF token.” but in this application there is no provision for that

Can anyone guide on this ?
