Awesome, I’m very glad to hear I could help with your app development! I figured that you would have had the app configuration setup already as you were generating Admin API tokens outside of the extensions already, but I did want to share the documentation and information on it just in case it helps.
This thread is marked as solved currently, but if you do have any further questions or issues with this topic, please do reply here and I can definitely help look into it further. If you have any issues with a specific API call returning an error or anything, please do also provide the x-request-id from the HTTP Response Header for us to find the call in our logs internally.
Regarding the UI issue with the reaction icons, thank you for the report of this, I am replicating this as well myself, and I will be sharing this with our team internally to help look into further!
