If your phone doesn't have this feature, you can still run multiple instances of your Android apps using a third-party app.
You should find this feature on Samsung, Xiaomi, and OnePlus phones. To make it clear, the feature to make multiple copies of an app is only available on certain Android devices. Here’s how you get duplicating your Android apps. You don’t even need a third-party app to make clones of your installed apps. This way, you can create a second copy of your favorite app, add your secondary account to it, and use that app as if it’s the original app you have on your phone. Do you have multiple accounts for an app but your Android phone will only let you use one? No worries, there’s a feature on some Android phones that lets you run multiple copies of an app.
