Angular Material Autocomplete Rounded Corners

Question

I am using Angular Material Autocomplete to do my search. I would like to format the corners to look more rounded, however I am having some issues with that. The first 2 pictures are what I'd like it to be and the last 2 pictures are my attempt. My main stylesheet is scss but if the assistance is in plain css, I will gladly accept. I will have no problems transforming to fit scss

This is my HTML

<div class="main-search">
    <form>
        <mat-form-field appearance="fill">
          <span class="input-min-text">Lookup Address</span>
          <input type="text" placeholder="Search"
            aria-label="Begin your search" matInput [formControl]="ResultsCtrl" [matAutocomplete]="auto"
            [(ngModel)]="searchInput">
          <!-- show this button only if the search box is empty -->
          <button *ngIf='!searchInput' matSuffix mat-icon-button aria-label="Search" class="button-1"><img
              src="../assets/icons/magnifying-glass-solid.svg" /></button>
          <!-- show this button only if the search box is not empty -->
          <button *ngIf='searchInput' matSuffix mat-icon-button aria-label="Clear" class="button-2"
            (click)="clearSearch()"><img src="../assets/icons/xmark-solid.svg" /></button>
          <mat-autocomplete #auto="matAutocomplete">
            <label class="results-heading">Results</label>
            <mat-option *ngFor="let results of filteredResults | async" [value]="results.add">
              <div>
                <span class="min-text">{{results.name}}</span>
                <span class="medium-text">{{results.add}}</span>
                <span class="min-text">{{locaresultstion.barcode}}</span>
              </div>
            </mat-option>
            <p class="min-grey-text">Additional text</p>
          </mat-autocomplete>
    
        </mat-form-field>
      </form>
    </div>
