Accidentally deleted app from my home screen

I wanted to temporarily delete huge casino, which is HUUUGE casino app from my home screen and reinstate it. I took it off and when I asked Siri to send me back to the home screen that app did not appear there I did eventually find it and tried to reload it, but it already said open, which means it’s still open. I went to my app library and the app shows there, but I cannot figure out how to get it back on my home screen what do I do? I have an iPhone 14 updated to 17.5.
