Is webgpu supported in version 0.9?

Hi,friends. I want to use webgpu to speed up my model on the web.I also found this webapp example.I tried to compile my model but got the following error. [Check failed: (bf != nullptr) is false: target.build.webgpu is not enabled.] Webgpu is not supported in version 0.9? Can you give me some advice to help me deploy the model to webgpu?

Best Regards.

Henry
