How to pass app environment variables to a Docker container?

I am using App Platform to deploy Spring Boot with Docker. I want to pass a variable to my Spring Boot app.

File: app.yml

name: my-app-name
region: ams3
services:
  - dockerfile_path: Dockerfile
    github:
      branch: BRANCH_NAME
      deploy_on_push: true
      repo: my_name/my_repo
    name: web

File: Dockerfile

FROM gradle:7.5-jdk17-alpine AS build
COPY --chown=gradle:gradle . /home/gradle/src
WORKDIR /home/gradle/src
ENV ACTIVE_PROFILE=APP_ACTIVE_PROFILE
RUN sh ./gradlew web:build --no-daemon

I want to pass APP_ACTIVE_PROFILE which is defined in my App-Level Environment Variables to my docker file.
