How can I run a custom docker image with multiple Lambda handlers?

Question

This is my dockerfile. I have also a app.py file with two handlers and I need to be able to run one of them based of a variable or similar. Right now I run only lambda.handler1, but also I want to run lambda.handler2

# Define global args
ARG FUNCTION_DIR="/home/app/"
ARG RUNTIME_VERSION="3.8"

# Bundle base image + runtime
FROM python:${RUNTIME_VERSION}-buster

# Include global args 
ARG FUNCTION_DIR
ARG RUNTIME_VERSION

# Install aws-lambda-cpp build dependencies
RUN apt-get update && \
  apt-get install -y \
  g++ \
  make \
  cmake \
  unzip \
  libcurl4-openssl-dev

# Install OCR build dependencies
RUN apt-get update \
  && apt-get install -y tesseract-ocr tesseract-ocr-spa \
  && apt-get install -y poppler-utils

RUN apt-get update \
  && apt-get install libgl1 -y

RUN python${RUNTIME_VERSION} -m pip install --upgrade pip
RUN python${RUNTIME_VERSION} -m pip install tesseract pillow pytesseract

# Copy handler function
RUN mkdir -p ${FUNCTION_DIR}
COPY app/* ${FUNCTION_DIR}

# Install Lambda Runtime Interface Client for Python
RUN python${RUNTIME_VERSION} -m pip install awslambdaric --target ${FUNCTION_DIR}
# Install the function's dependencies
RUN python${RUNTIME_VERSION} -m pip install -r ${FUNCTION_DIR}/docker-requirements.txt

# Set working directory to function root directory
WORKDIR ${FUNCTION_DIR}

# (Optional) Add Lambda Runtime Interface Emulator and use a script in the ENTRYPOINT for simpler local runs
ADD https://github.com/aws/aws-lambda-runtime-interface-emulator/releases/latest/download/aws-lambda-rie /usr/bin/aws-lambda-rie
COPY entry.sh /
RUN chmod 755 /usr/bin/aws-lambda-rie /entry.sh

ENTRYPOINT [ "/entry.sh"]
CMD [ "app.lambda_handler1" ]
