gitlab runner couldn't download files that uploaded by another project

Question

I have two projects, both configed s3 cache

[runners.cache]
    Type = "s3"
    Shared = true
    [runners.cache.s3]
      ServerAddress = "10.0.211.191:9000"
      AccessKey = "TWbEUtjH6EQViU67"
      SecretKey = "****************"
      BucketName = "test"
      Insecure = true
    [runners.cache.gcs]
    [runners.cache.azure]

Project A's gitlab-ci.yml

android_jni_build:
  stage: build
  tags: [build,for_android]
  cache:
    - key: $CI_COMMIT_BRANCH-android_jni_build
      paths:
        - output
      policy: push
    - key: android_auto_test
      paths:
        - output/android/apk
      policy: push
  script:
    - set -eu
    - bash $CI_PROJECT_DIR/build/android/build_jni.sh x86
    - bash $CI_PROJECT_DIR/build/android/build_jni.sh x86_64
    - bash $CI_PROJECT_DIR/build/android/build_jni.sh armeabi
    - bash $CI_PROJECT_DIR/build/android/build_jni.sh armeabi-v7a
    - bash $CI_PROJECT_DIR/build/android/build_jni.sh arm64
    - bash $CI_PROJECT_DIR/build/android/build_apk.sh
    
android_test:
  stage: test
  needs: 
    - android_jni_build
  trigger: 
    project: projectB
    branch: auto_test

Project B's gitlab-ci.yml

AndroidTest:
  stage: test
  tags: [android,autotest]
  cache:
    key: android_auto_test
    paths:
      - output/android/apk
    policy: pull
  script:
    - set -eu
    - python run.py

Project A can upload apk files, but Project B couldn't download apk files, and I saw Project A upload to http://10.0.211.191:9000/test/project/4353/android_auto_test, I guess only Project A's other job can download files because project/4353...

Is there any other way to figure out it?
