Updating a Ledvance zigbee bulb firmware

Picking up from this remark

I have been trying to understand the zigbee firmware update process better.
I have a ledvance bulb on the generic zigbee bulb driver that shows the update firmware button.


From the post of Mike Maxwell i understand that it only shows if there is an update available.
However, clicking the button shows no response in the logging…

Am i understanding this wrong or should i do something differently?

The command is always there available update or not.
When the command is clicked any action is sent to the live logs.

@mike.maxwell thank you for that clarification
