[Automation in non-rooted android smartphone]

Can you make videos on automation in non-rooted android smartphone remotely??

We know, we can write a bash/shell script and send it to someone remotely via link, if he/she clicks on link, the script will automatically execute.

Can we do same in non-rooted android smartphone too??

For an instance, can we send a link to someone with a non-rooted android smartphone , if he/she clicks on link, automatically his/her email account will open, automatically a message will be written in email and it will be sent automatically.
Is it possible??

I think it is same as rubber ducky
