I want to add a year view to a fullcalendar. I can add day, month and week. 

Below is my code.

<template>
  <div class="slds-grid slds-gutters">
    <div class="slds-col">
      <span>
        <lightning-card  title="Other">
          <p class="slds-p-horizontal_small">
          <lightning-input type="date" name="input1" label="Start date" ></lightning-input>
          <lightning-input type="date" name="input1" label="End date" ></lightning-input>
        </p> 
      </lightning-card>
      </span>
      <lightning-button variant="brand" label="Apply" title="Primary action" onclick={handleClick} class="slds-m-left_x-small"></lightning-button>
    </div>
  </div>

    <div class="slds-box outerPart">
      
      <p class="slds-m-bottom_small">Opportunity Visualizer</p>
      <!--lightning-button variant="brand" name="verifyMail" label="Sync Salesforce Tasks" onclick​={initialiseFullCalendarJs}></lightning-button-->
      <div style="background:#ffffff;" class="slds-grid slds-m-top_medium">
        <div id="calendar" class="fullcalendarjs"></div>
      </div>
      <div if:true={casesSpinner} class="slds-spinner_inline spinner-padding">
        <lightning-spinner variant="brand" 
                           alternative-text="Loading Cases"     
                           size="medium">
        </lightning-spinner>
    </div>
    </div>
  </template>

import { LightningElement, track } from 'lwc';

    });
    }
    const ele = this.template.querySelector('div.fullcalendarjs');
    // eslint-disable-next-line no-undef
    $(ele).fullCalendar({
      header: {
          left: 'prev,next today',
          center: 'title',
          right: 'month,basicWeek,basicDay'
      },
     // defaultDate: '2020-03-12',
      defaultDate: new Date(), // default day is today
      navLinks: true, // can click day/week names to navigate views
      editable: true,
      eventLimit: true, // allow "more" link when too many events
      events : this.finalOppo
    });
  }
  getTasks(){
    getOppo()
        .then(result =>{   
           this.returnedOppo = JSON.parse(result);
           this.casesSpinner = false;
            this.initialiseFullCalendarJs();
            this.error = undefined;
        })
        .catch(error => {
            this.error = error;
            this.outputResult = undefined;
        });
  }
}

Output : 

How do I add the year view?
