Conda activate repetitive error on MacOS

I constantly get the following error upon conda activate base on my MacOS Monterey iTerm2 terminals:

% conda activate base

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

Steps I have taken so far:

0-Extensive google search!

1- Tried conda init :

% conda init
no change     /Users/myname/miniconda3/condabin/conda
no change     /Users/myname/miniconda3/bin/conda
no change     /Users/myname/miniconda3/bin/conda-env
no change     /Users/myname/miniconda3/bin/activate
no change     /Users/myname/miniconda3/bin/deactivate
no change     /Users/myname/miniconda3/etc/profile.d/conda.sh
no change     /Users/myname/miniconda3/etc/fish/conf.d/conda.fish
no change     /Users/myname/miniconda3/shell/condabin/Conda.psm1
no change     /Users/myname/miniconda3/shell/condabin/conda-hook.ps1
no change     /Users/myname/miniconda3/lib/python3.10/site-packages/xontrib/conda.xsh
no change     /Users/myname/miniconda3/etc/profile.d/conda.csh
no change     /Users/myname/.bash_profile
No action taken.

2- Uninstalled AND re-installed a fresh miniconda (I did this several times)

3- Switched my shell from zsh to bash and vice versa

4- Uninstalled AND re-installed iTerm2 (the powerful and famous terminal app on MacOS, which is my default terminal app)

5- Followed this post:

% source ~/miniconda3/etc/profile.d/conda.sh

/Users/myname/miniconda3/etc/profile.d/conda.sh:21: parse error near `}'

6- Added/commented following lines to ~/.zshrc :

source ~/.bash_profile
export PATH="/Users/ruhollah/miniconda3/bin:$PATH"
