Element is not interactable, tried with multiple locators

I'm using Protractor tool, and coding is done in JavaScript. Scenario- Go to -https://ift.tt/38CPY0y

Click on Contribute Now button->Fill the form with valid inputs-> And click on Proceed to pay button-> Click on Netbanking -> And click on any Bank

I'm not able to click on the bank button

Line of code-

it('Test with NetBanking Options', function ()

{

     var elm3 = element(by.xpath("//app-main-payment[@class='ng-star-inserted'] //span[contains(text(),'Net Banking')]"));

     browser.executeScript("arguments[0].click()", elm3);
     browser.sleep(6000);
     //element(by.className("mat-stroked-button NB_ICICI")).click();
     //var elm4 = element(by.xpath("//div[@class='mat-button-ripple mat-ripple'] //div[contains(text(),'HDFC')]"));
    // browser.executeScript("arguments[0].click()", elm4); 
    // var elm5 =element(by.xpath("//section[@class='ng-star-inserted'] //button[@class='mat-stroked-button NB_AXIS']"));
      //var elm5 =element(by.xpath("//section[@class='ng-star-inserted'] //div[contains(text(),'HDFC')]"));
   var elm5 =element(by.xpath("//div[@class='bank-icons ng-star-inserted'] //button[@class='mat-stroked-button NB_AXIS']"));
  
     browser.executeScript("arguments[0].click()", elm5);   
     browser.sleep(5000);
     browser.getCurrentUrl().then(function(url){
            if(url.indexOf("axis") >= 0 ){
             console.log("Payment with NetBanking option passed Successfully!");
           }else{
            console.log("Payment with NetBanking Option Failed");
          }
        })
        
         browser.sleep(5000);
    })

As shown above, I have tried multiple locators combination but I'm getting only one error message-

"Element is not interactable"

Please help, thanks in advance
