Hi, @PosXanTivity. I'm not sure why these particular apps are accessing your clipboard.
However, the alert you are seeing is an Android 12 feature and just lets you see which apps are accessing your clipboard - and lets you decide whether that is warranted on a case-by-case basis. It gives you a degree of control.
Apparently, all Android apps have the facility to read your clipboard, and it may be needed for their own functionality in some instances.
To find the setting (and toggle it off, should you wish to do so), please head to Settings > Privacy > and look for the toggle Alert when clipboard accessed.
