Spamed by Google Assistant and Gemini messages: I can't stop hundred notifications per hour. My Google Assistant and Google notifications are disabled

This morning my smartphone (an A55, Android 14 (6.1.43-Android14-1)) is spamming notifications inviting me to try the Gemini AI and/or to use Google Assistant. - My Google Assistant is disabled in my account - Google and Google Play aren't allowed to send normal notifications - Google isn't allowed to send notification when its screen is locked I've rebooted my phone. But I'm receiving __more than one hundred notifications per hour__ interrupting my work as a popup, or doing a bip, while appearing on my locked screen. Like: - "_Google Assistant is ready to help you, Activate_", - "_Try: Say 'what the weather?' to Gemini_" - "_Say: 'How to set an alarm to 7am?' to Gemini_" Endlessly, on the locked screen. How to stop these notifications coming?
