Adding pagination to search results

So I just recently created a search.php to be able to customize my search results. However when I did that the pagination dissapeared. I have tried to find something but I can’t. It’s all just people having problems with plugins that I don’t care to use. I’m only looking for the standard pagination for the twenty twenty theme or something similar. Thank’s in advance!

A bit about my site: it’s localhosted so i can’t link it, I am using the twenty twenty theme and if necessary i could paste my search.php code here. Also I’m fairly new to programming which I guess is good to know.
