No Result from LWC Function Calling

I'm calling getLognotes() on click of button but it's showing nothing in console. I tried to call it from connected callback but when I do that the whole page gets disappear, so I tried button click approach but no go. Even 'Hi' is not getting printed so I think on I'm not even getting inside function.
  
import { LightningElement, track,api, wire } from 'lwc';
import getContentNote from '@salesforce/apex/TBT_SupervisorLog.getContentNote';


export default class tBT_SessionGuideline extends LightningElement {


// connectedCallback(){
//     this._getLogNotes(); // this not working
// }

_getLogNotes(){
    getLogNotes(action).then(res => {
        this.getContentNote = res;
        console.log('hi');
        console.log("content notes result", this.getContentNote);
    }).catch((error)=>{
        console.error("content notes error " ,JSON.stringify(error));
    })
}


*My apex class*
public with sharing class TBT_SupervisorLog {

@AuraEnabled(Cacheable=true)
public static List<ContentNote> getContentNote(){
Set<Id> contactIds = new Set<Id>();
contactIds.add('0030100000ABCD');

Set<Id> contentLinkIds = new Set<Id>();

for(ContentDocumentLink conLink : [SELECT ContentDocumentId FROM ContentDocumentLink WHERE LinkedEntityId IN :contactIds]){
    contentLinkIds.add(conLink.ContentDocumentId);
}
List<ContentNote> NoteList = [select id, ContentModifiedDate,  LastModifiedBy.name from ContentNote where Id IN : contentLinkIds ];
    System.debug(NoteList);  
return NoteList;
    }
}
I checked in debug log it's fetching result from class.Please if someone could guide.

Hello Abhishek,

There are some issues with your code , Can you try with below :
  
import { LightningElement, track, api, wire } from 'lwc';
import getContentNote from '@salesforce/apex/TBT_SupervisorLog.getContentNote';

export default class TBT_SessionGuideline extends LightningElement {
    @track getContentNote;

    @wire(getContentNote)
    wiredGetContentNote({ data, error }) {
        if (data) {
            this.getContentNote = data;
            console.log('Content notes result:', this.getContentNote);
        } else if (error) {
            console.error('Content notes error:', error);
        }
    }

    handleButtonClick() {
        getContentNote({ action: 'getLogNotes' })
            .then((result) => {
                console.log('Content notes result:', result);
            })
            .catch((error) => {
