+  on = "push"
+}
+
+action "Filter branch" {
+  uses = "actions/bin/filter@24a566c2524e05ebedadef0a285f72dc9b631411"
+  args = "branch staging"
+}
+
+action "git-pr-release" {
+  uses = "bakunyo/git-pr-release-action@master"
+  needs = ["Filter branch"]
+  secrets = [
+    "GIT_PR_RELEASE_TOKEN",
+    "GITHUB_TOKEN",
+  ]
+}
+```
