Use the display: flex
along with the justify-content:
center in a parent element.
So display the result you expect, see in the example I left below.
I hope I’ve helped.
#id-text{
display: flex;
justify-content: center;
}
<div id="id-text">
<h1>GroupTCC</h1>
</div>
But the file is inside Androidmanifest.xml where I believe this formatting is not valid, I will attach code photo to the question
