Building App for iOS for free, for Personal Use

Hi, I am working on a Project for College and right now I don’t plan to release the application commercially. I have recently ejected my Expo app as Bare workflow to implement some third-party BLE Bluetooth library/package. I have developed the app using the React Native framework and after my ejection, I have run Pod install and implemented the native libraries along with the BLE Bluetooth package. I want to be able to test my app on my personal iPhone to see if the codes work while working to finish the app.

I am really in need of help & guidance on how to build the app for free and test it on my device, as I understand the Expo client on iOS does not provide support to access the native libraries, or more specifically, access the Bluetooth function on my device.
