View reference
When a (button) library name is selected or clicked, I want the next inactive button to become active (turn bright red).
I googled and found that there is a (blur) and (focus) event in angular

You can disable and enable buttons via JavaScript:
const normalButton = document.querySelector('.normal');
const disabledButton = document.querySelector('.disabled');
disabledButton.disabled = true;
normalButton.addEventListener("click", ()=> {
disabledButton.disabled = false;
})
Click on 'aaaa' button to enable the other button
