Auto-fill credential at login

Hello Everyone,
I have a demand from client to implement auto-fill password while user comes again to login and at first time app should display native popover to ask for save credentials to key-chain for ios and secure storage for android to use in future. I tried many ways like writing proper HTML input fields with appropriate attributes like autocomplete and textContentType.
Also in research I found an integration with associative domain to integrate auto-fill but still I am not able to make this workable. Please share your valuable suggestions.
I am using ionic(5) - capacitor(7) with angular.

Thanks and regards,
Parth

Have you reviewed the guide?

Yes @twestrick I followed same process and it is working for android but somehow its not working for ios. I configured the applinks: domain in xcode and associated domain file for server and used npm install capacitor-ios-autofill-save-password to save credentials manually in iCloud key chain. Now, code is waiting for native prompt using plugin but prompt is not displaying.
