Google Gmail on Android 12 now only share e-mail attachments with WhatsApp

A short while ago, on my Motorola cell phone, when I opened up an e-mail attachment I could select which app I would use to share the file/photo with. I was used to share through **WhatsApp**, but accidentally I checked an option to always share via WhatsApp. Now I cannot revert it back, so that I can choose another app to do the sharing with. By chance, someone ever found out a way to restore the choice of apps when sharing a e-mail attachment through Google Gmail on Android 12 ? I've searched through Google Gmail settings, but to no avail thus far.
