How to click outside button and keep active style? - AlpineJS & TailwindCSS - css

Question

I'm using TailwindCSS and AlpineJS on this project. There are two buttons that switch tabs and the first one have autofocus. When a tab is switched, the other button becomes active:
I want the button to become inactive only when the other button is clicked. Is there a way to do this using AlpineJS and TailwindCSS? Something like bind the active class with #click.away.
Thanks in advance.
Here is my code:
<div class="flex flex-col">
<div class="-my-2 overflow-x-auto sm:-mx-6 lg:-mx-8">
<div class="inline-block min-w-full py-2 align-middle sm:px-6 lg:px-8">
<div x-data="{ openTab: 1, coin: 0 }" class="overflow-hidden border-b border-gray-200 shadow sm:rounded-lg">
<div class="flex items-center justify-between px-10 py-8 bg-white wrapper">
<div>
<h3 class="lg:text-2xl sm:text-lg">Saldos</h3>

You can toggle classes using the Alpine.js x-bind:class object syntax, eg. :class="{ 'active classes': openTab === 1 }" for your first tab, see the following snippet. You could also bind :disabled="openTab !== 1" to disable the button (for the first button).
<div aria-label="Lista" data-balloon-pos="up" id="show-tip">
<button :class="{ 'active classes': openTab === 1 }" class="p-1 mr-1 text-gray-500 rounded-lg outline-none active:text-gray-200 hover:text-gray-200 focus:text-gray-200 focus:outline-none hover:bg-gray-700 focus:bg-gray-700" type="button" #click="openTab = 1" autofocus>
<svg class="w-6 h-6" fill="currentColor" viewBox="0 0 20 20" xmlns="http://www.w3.org/2000/svg"><path d="M9 2a1 1 0 000 2h2a1 1 0 100-2H9z"></path><path fill-rule="evenodd" d="M4 5a2 2 0 012-2 3 3 0 003 3h2a3 3 0 003-3 2 2 0 012 2v11a2 2 0 01-2 2H6a2 2 0 01-2-2V5zm3 4a1 1 0 000 2h.01a1 1 0 100-2H7zm3 0a1 1 0 000 2h3a1 1 0 100-2h-3zm-3 4a1 1 0 100 2h.01a1 1 0 100-2H7zm3 0a1 1 0 100 2h3a1 1 0 100-2h-3z" clip-rule="evenodd"></path></svg>
