Hi @魏嘉宏
Please try to create it in Power Automate. If the flow still cannot be created in Power Automate, the problem should be in Power Automate. To better assist you, we recommend going to the Power Automate forum for more help.
If the flow is successfully created on Power Automate, then the problem is with Teams. Please try clearing the Teams cache and logging in again.
Additionally, if you need to add this connector to a channel, you can also add it in the channel settings.
