iCalendar format link added to the email

Your software
My Mautic version is: 3.1.2
My PHP version is: 7.3.27
My Database type and version is: mysqilnd 5.2.12-dev

Your problem
My problem is: Is there a way to put an iCalendar Format (*.ics) link in the email?

These errors are showing in the log:

Steps I have tried to fix the problem:

Hi, you can attach it. Go to your emai, open it, then adadvanced tab and add attachment.
Alternatively you can upload the ics file as an attachment, upload as an asset into Mautic, and refer to that link via the Mautic tokan called “assetlink”.
