How could I answer the twofactor message on Nextcloud Client in Ubuntu

I activated the Two-Factor auth over the Desktop app.
I receive the desktop app on Ubuntu. But If I click on the notification nothing happened.

nextcloud-desktop/lunar,now 3.7.3-1 amd64  [installiert]

I’m afraid I don’t fully follow what you did and what you’re experiencing.

Which app did you activate?

See Two Factor Authentication in Nextcloud

I found the solution. It seems my Nextcloud app in Ubuntu is too old. I closed this Nextcloud. Downloaded a recent version as AppImage and started this. Now I received the message.
After that I was able to answer and login.
