I bought Minecraft back in 2019, but now it won’t let me redownload it. What do I do?

Just as the title says, I bought Minecraft PE back in 2019 but uninstalled it because I lost interest in the game for a while. Now I want to download it again, but the App Store only gives me the option to buy it. What can I do? I’m using the same Apple ID I bought it in back in 2019.
