PWA Dynamic doesn't work

I installed PWA Dynamic and after adding the button, I also set up Install PWA A via Workflow.
I also added manifest and service-worker.js, but after clicking the button, I only get a toast message, not a message asking me to add the app to the home screen. Can anyone help me figure out what to do here?

Hi @hackingrowth, you should be able to fix this by setting a workflow to run on page load which calls the manifest you’ve uploaded, so your app is actually running the JavaScript. The name of the workflow action is ‘Append Manifest PWA’.

I’ve dropped a screenshot example of how it’s set up in one of my apps below:

Thank you for your reply! @grgrsmth . I’ve already done that setting, but when I clicked the pwa button there is no action triggered.

In this case, what should I do?
