Matt Dean thanks a lot for your immediate response. will check the errors in console since it's showing Typeerror: cannot read properties of null for navigation.

Matt Dean I have tried using '_self', window.location.replace, window.location.href, window.location.assign all did not work for opening the link in the same tab. '_self' is opening current page what is opened in website but not the respective page of the link after clicking on the link. Kindly provide some other solution.

Yes Matt Dean I have tried this but due to window.open it's opening in new tab not in the same tab. Kindly provide some other solution to open link in same tab.

Kindly upload the code for opening button in same tab with proper navigation of respective page of button selected
