[Python] Check if conda env exists and create if not in bash

I have a build script to run a simple python app. I am trying to set it up that it will run for any user that has conda installed and in their PATH. No other prerequisites. I have that pretty much accomplished but would like to make it more efficient for returning users.

build_run.sh

conda init bash
conda env create --name RUN_ENV --file ../run_env.yml -q --force
conda activate RUN_ENV
python run_app.py
conda deactivate


I would like to make it that the script checks if RUN_ENV already exists and activates it instead of forcing its creation every time. I tried

ENVS=$(conda env list | awk '{print }' )
if [[ conda env list = *"RUN_ENV"* ]]; then
conda activate RUN_ENV
else
conda env create --name RUN_ENV --file ../run_env.yml -q
conda activate RUN_ENV
exit
fi;
python run_app.py
conda deactivate


but it always came back as false and tried to create RUN_ENV
