Unable to Pair Schlage lock (Model BE468) to HA, New User

I have Pi 5, and installed HAOS (latest version) on SSD, and I am totally new to HA. I am trying to add Schlage door lock (Model BE468), all my attempts failed. I have Aeotec Z-Stick 7. The lock is apparently sending code (green checkmark on keypad of the door), but Z-Wave Inclusion fails even after 5 minutes. I had the z stick 7 taped to the door lock, Pi 5 within inches of the door. Please help me. Thanks.

Do you have any other Z-Wave devices paired/included? Have you tried "excluding" the lock or resetting it?

The door lock is the my first device I was trying to add, which was unsuccessful. I have factory reset first, then I tried "excluding" lock. I did notice green check mark on my door lock keypad. After this, I tried include, which was unsuccessful. Is there some sort of message in HA that lock is cleared following excluding procedure?

Please read here, the BE468 is similar to the BE469 in terms of Zwave:

No. This is my first try to include

Thanks to all, with your tips/suggestion, I successfully added my door lock, tried/tested, it works. Thanks once again.
