How to trim "Surname" text (remove all characters except the 1st one) and display "S." only

Anna Sho

I need to return trimmed surname in endpoint.
Ive tried to search documentation  but I haven't found exact solution for my case.

Thank you

 I might combine a couple filters. First, split - you can take your text string and transform it to an array. Likely use a space as a separator. Secondly, the filter last to return the last entry of the array which would be the last name.
