angular - How do I send select option value as parameter to the api?

Question

how can I send the option values in a select as a parameter to the backend?

I have implemented the following:

 <div class="select-wrapper">
   <select class="action_slc" required title="" formControlName="action">
       <!-- Options -->
        <option value="content" *ngFor="let action of actionOptions" [value]="action.value">
         {{ action.viewValue }}
         </option>
     </select>
   <div class="select_arrow"></div>
  </div>

public actionOptions: any[] = [
    { value: '1', viewValue: 'enable' },
    { value: '0', viewValue: 'disable' }
  ];

userActivision(userId: string, activision: string) {
    return this.http.patch<any>(`${environment.baseUrl}/users/activision/${userId}?activision=${activision}`, { // {activision} ist the value in actOptions
      headers: new HttpHeaders({
        'Content-Type': 'application/json'
      })
    }).pipe(map(data => data));
  }

 this.service.userActivision(userId, activision).subscribe( (data: any) => {
        console.log('Data:', data);
        if (data && data.userId === userId) {
          successCount += 1;
        }
        next(index + 1);
      });
