Unable to start emulator from command line

I am trying to run the below shell script:

#!/usr/bin/env bash

sdkmanager "emulator" "system-images;android-28;google_apis_playstore;x86_64"
echo no | avdmanager create avd -n "Android" -k "system-images;android-28;google_apis_playstore;x86_64" --device 'Nexus 6P'
$ANDROID_HOME/tools/emulator -avd Android -no-audio -no-boot-anim -no-snapshot -timezone Asia/Phnom_penh

I have added the ANDROID_HOME, ANDROID_AVD_HOME to my PATH (Note: I am using macos with zsh) and i have sourced the zshrc file and also restarted the terminal but keep getting the below error:

./start_emulator.sh: line 3: sdkmanager: command not found

./start_emulator.sh: line 4: avdmanager: command not found

PANIC: Unknown AVD name [ANDROID], use -list-avds to see valid list. ANDROID_AVD_HOME is defined but there is no file Android.ini in $ANDROID_AVD_HOME/.android/avd (Note: Directories are searched in the order $ANDROID_AVD_HOME, $ANDROID_SDK_HOME/avd, and $HOME/.android/avd)
