If you want to try getting your device connected, let me know:

This is the most straightforward answer. If you rely on Discord daily, investing in a newer Android device is the best course of action. You don't need a flagship phone; many affordable budget Android phones running Android 10 or later are readily available. Even a used device from the last 3-4 years will run the latest Discord app flawlessly and keep you secure.

Using modified or third-party Discord clients can violate Discord’s Terms of Service and get your account banned.

Before you start, go to on your Android 4.4.4 device and enable "Unknown Sources" (sometimes called "Install from unknown apps").
