Xcode Archive API Key Error

I am creating an AI powered mobile application for my university dissertation that utilises Google Gemini in order to generate tailored responses with a prerequisite prompt. In order to facilitate this, I use an API key which allows the communication to be made. I received an email upon archiving my application that informed me that:

ITMS-90683: Missing purpose string in Info.plist - Your app’s code references one or more APIs that access sensitive user data, or the app has one or more entitlements that permit such access. The Info.plist file for the “Amrit AI.app” bundle should contain a NSSpeechRecognitionUsageDescription key with a user-facing purpose string explaining clearly and completely why your app needs the data. If you’re using external libraries or SDKs, they may reference APIs that require a purpose string. While your app might not use these APIs, a purpose string is still required."

I have since made the adjustments to my info.plist by adding a description as to why the API key is being used. However, it still has not rectified the issue. I have contacted multiple apple support lines and none of them have been able to help with my error. I am under extreme pressure to upload this application to the App Store before my dissertation deadline as the reviews are critical to my evaluation section. Any help would be much appreciated.

Attached is a screenshot of my Xcode information property list and im not sure why this isn't being accepted
