Forgot to replace metal tab

I have just finished replacing the battery and the screen one this smartphone and it took me forever !!! Unfortunately I forgot to put back the metal tab that holds the screen and fingerprint cable and I am wondering if that is going to be an issue for me in the future as I really don’t want to open the device again !!!

please let me know if I have to reopen my device again and put back or if it is going to be fine without it for now ???

Thanks in advance for your help
