biblatex what is the delimiter between author and title in the bibliography for verbose-inote

Question

I would like to add a comma and space as the delimiter between the author key and the title key for entries in the bibliography, I am using verbose-inote as the biblatex style. I tried, without success:

\renewcommand*{\nametitledelim}{\addcomma\space}

I can't find the right delimiter in the

3.11 Formatting Commands

and

3.11.1 Generic Commands and Hooks

sections of the biblatex documentation.

nametitledelim is a context-sensitive delimiter and should be redefined with \DeclareDelimFormat. In the bibliography context bib, nametitledelim falls back to \labelnamepunct (which in turn is \newunitpunct by default) for backwards compatibility reasons, so you have to explicitly redefine nametitledelim in the bib context if you want to affect the bibliography.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=verbose-inote, backend=biber]{biblatex}

\DeclareDelimFormat[bib]{nametitledelim}{\addcomma\space}

\addbibresource{biblatex-examples.bib}
