On Android devices, you can easily install the app via Chrome, Edge, or any modern browser.
First, get your app link from either the Setup Apps on Desktop/Phone default method guide or the Setup Apps on desktop/phone (Custom Page Method) guide. Use this link in the next steps.
Steps:
Open Chrome and go to the link you got from guided setup (like https://your-site-name/notiqoo-chat/)
A download / install (Add to Home Screen) prompt will automatically appear.
Tap Install / Add.
The Notiqoo app will be added to your Android home screen with its own icon.
After that login with credentials.
