Using a function in my blueprint (info field text property)

I want to set the return of a php function (showing the content of a log file) as text for my info field. {{ ??? }} Is that possible? I am struggeling to find a way. :exploding_head:

Not via a function. You would need a custom page method or page model method

Thank you!!

PS: Would be great to find a snippet in the docs, of how to use it in blueprints.
