How to create a form with a text field where characters are in separated boxes?

Question

I would like to create a form (at least printable) containing a field where each character is separated from the previous one.

Something similar to the field A in this picture :

What is the name of this type of field ? And/Or what is the option to activate ?

Is there a way to make this version (with unclosed box) :

Thank you very much !

EDIT : if the digital version creating a form in PDF is not possible... is there a way to create only a graphical field ?

these are comb fields, you get them e.g. with \TextField[comb,maxlen=3,name=accountA,width=3em]{} — Ulrike Fischer, Jan 31 '22 at 17:40

When using l3pdffields, you can use

\DocumentMetadata{} %loads pdfmanagement-testphase
\documentclass{article}
\usepackage{l3pdffield-testphase} % for form fields
\begin{document}
\ExplSyntaxOn
\pdffield_textfield:n{MaxLen=3,setfieldflags={comb},name=accountA,width=3em}
\ExplSyntaxOff
\end{document}

Thanks to Ulrik Fischer, I now know it is named "comb fields".

To make something like field A (full closed cells) :

\TextField[comb,maxlen=3,name=accountA,width=3em]{}

@wipet : I believe it is found in the "hyperref" package. I found multiple examples using it with this. (I completely forgot where I needed the CombField)
