Can't connect to Harmony hub

I have a problem trying to connect my SmartThings hub V3 (UK model) to my Logitech Harmony hub. According to this https://support.smartthings.com/hc/en-us/articles/205653834-Logitech-Harmony-Home-Hub there should be Logitech on the device list but there isn’t any.

How can I make the connection? Any help is appreciated. Thanks!

Welcome to SmartThings! Can you post a screenshot of the Add Device page that you see?

I assume you are not in the UK? If not, SmartThings may not offer it as an option in regions outside the UK. You should contact ST support at https://support.smartthings.com

No, I’m not in the UK. I’ll try the support.

Thanks!

You can just change the region to US, I leave in Europe and I moved my account to US in order to have everything available.
So far I have:
ST HUB V3 purchased from US
Amazon Alexa purchased from US
Philips HUE Hub + Lightstrip purchased from Europe
Harmony Hub purchased from US
Ikea bulbs purchased from EU
Motion sensors, water leak sensors, arrival sensors purchased from US

And everything is working fine
