OH3 mail sending: send mail content opening specific iOS App

I installed the mail binding and configured the SMTP server to send mails using GMail thanks to the guide from @rlkoshak.

Now it is not an OH question but the use case might be covered by somebody already.

I have a robot vacuum cleaner. Whenever the smart plug is turned ON it starts charging and sends a mail after charging. What I want to do is to actually send an email body which by clicking on a Link (or whatever is required in the mail body) opens up a specific App if installed on the users phone.

Does anybody have experience with something like this in iOS?

does html - Links to open apps in iOS - Stack Overflow help? Did not try such thing myself though…
