Issues with NetworkManager-openconnect during installation

I’m trying to install KDE Plasma on a Rocky Linux 8.8 system. However, the installation is producing the following error:

$ sudo dnf install @kde-desktop

 Problem: conflicting requests
  - nothing provides NetworkManager-openconnect needed by plasma-nm-openconnect-5.24.7-1.el8.aarch64

NOTE: I tried installing GitHub - NetworkManager/NetworkManager-openconnect: network-manager-openconnect but that didn’t fix the problem.
