locked out with upgrade to version 7

In sum: I can't use the app because I haven't updated my iOS, and 1Password updated automatically to a version that needs a higher level iOS. 1Password had said I can continue to use the old app but I don't see how to restore it.

Details: An email arrived on January 21 telling me that I should upgrade my iOS to at least Mac OS Monterey 12 in order to run the new version of 1Password.

It goes on to say: If you cannot update your device to macOS 12 or higher, 1Password for macOS will still work. However, you will no longer receive app updates.

I haven't had time to do the update and tonight I cannot run 1Password.  I click on the icon and the message reads:  "You can’t use this version of the application “1Password.app” with this version of macOS. You have macOS 11.7.10. The application requires macOS 12.0 or later."

I do not see on the website where I can download a legacy version so that I can keep running 1Password until I'm able to update to a higher OS. 

Any suggestions?
