Hack Messenger and WhatsApp connection

I received a friend request on Facebook and mistakenly accepted it. Then, when I replied on Messenger, codes appeared on the screen. I realized it was a hack; the hacker shares his screen and uses a Trojan to try passwords. I didn't share or attempt the hack, but the correct action was to log out from my account. I completely deleted Facebook and Messenger, then downloaded Facebook Lite from the store, logged in, enabled two-step verification, and blocked the hacker. The login codes became useless. If this happens to you, don't try to log in again or contact Facebook or Messenger. At that time, you must delete the app. If it happens with WhatsApp, you should download WhatsApp Business or use incognito mode in the browser. Every attempt brings you closer to the hacker, who can then read your screen and plant malware that remains even after logging out, stealing financial information, phone numbers, and emails. The first step is to delete the compromised app. I hope at least one person benefits; I would be grateful. "He who guides to good is like the doer of it."
