Can't I use the secret value of the repository when using the Github Action of another repository?

I’m making a Github Action for the launch of Marketplace.

Can’t I use the secret value of the repository when using the Github Action of another repository?

In other words, I want to use the secret value of the repository to be called, not the secret value of the calling side.

I want to do it in a way other than this.
because the secret value of the Jay-flow/relay-schema-bot repository is not used.

name: Relay Schema bot

on:
  push:
    branches:
      - master
    paths:
      - 'schema.graphql'

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: Jay-flow/relay-schema-bot@master
        with:
          token: ${{ secrets.PAT }}
          repo-url: https://github.com/Jay-flow/artifacts-pro

          # I don't want to enter it as below.
          # because the secret value of the Jay-flow/relay-schema-bot repository is not used.
          app-id: ${{ secrets.APP_ID }}
          app-private-key: ${{ secrets.APP_PRIVATE_KEY }}

The APP_PRIVATE_KEY value is required to make a pull request from the Github application I created. The problem is that the user should not know this value.
Is there any way to make this possible?
