Unable to Unlock via Alexa or Google Home

I have the Ultraloq Lever model, working fine with the wifi bridge via the Xthings Home app. I have also linked it to both Alexa and Google Home. I can see the lock in both apps, but I couldn’t figure out how to unlock it. Whenever I create a routine or automation, I can only find an option to lock the door but not to unlock it. Is that a security feature or am I missing something?

Thanks.
