Does not delete webpixel from a store

I am using the below mutation to delete the WebPixel but it’s is not removed from the store.

mutation {
  webPixelDelete(id: "gid://shopify/WebPixel/193") {
    deletedWebPixelId
    userErrors {
      field
      message
    }
  }
}

Every time I reinstall, the old extension still remains active with adding the newly published extension.

Do you think it’s a bug?
