texindy style: How do I fill the lines with dots?

I would like to build an a few Indices for a document that contain names in several languages. I understand from reading around that the way to go is imakeidx and to use texindy for the processing…since previous packages have problems with multiple indices and even ordering on foreign languages.

I got most of it working, except for one issue — placing dots (ellipsis) between the end of the words and the page numbers.

I first tried man texindy on a version 2.5.1 that comes with TL’20. That sends the reader to "The LaTeX Companion (2nd ed.)" of some 15 years ago … so I got that. But that sends one to the web-site xindy.org and even after that I can’t get a good hold on how to do this simple task — fill the spaces between the end of the line and the page number with dots as in:

fruit ........ 7
   apple .....11
   banana ....13

I have been able to work it out all the way to:

documentclass{article}
usepackage{makeidx}
makeindex
letlettergrouptextbf
usepackage{filecontents}

begin{document}
begin{filecontents*}{mal-style.xdy}
(markup-index :open  "begin{theindex}~n"
    :close "~n~nend{theindex}~n"
    :tree)

(markup-indexentry :open "~nitem " :close "" :depth 0)
(markup-indexentry :open "~n  subitem " :close "" :depth 1)
(markup-indexentry :open "~n    subsubitem " :close "" :depth 2)
(markup-locclass-list :open "dotfill " :sep ", " :close "")
(markup-locref-list   :sep ", ")
end{filecontents*}

index{premier niveau}
index{niveau!1@premier}
index{niveau!2@deuxième}
index{niveau!1@premier!1@premier}
index{niveau!1@premier!2@deuxième}
index{étrangères}
index{Ça va}
index{À quelle}

printindex
My first paragraphldots
end{document}

which is a simplification of the code by @Mailipivo here texindy equivalence to makeindex settings.

It uses makeidx and works fine and uses the Module to produce the dots unde xindy, but I have not been able to move it to imakeidx so I can use it for multiple indexes.

documentclass{article}

usepackage[xindy]{imakeidx}
   makeindex[name=std, title=Remissivo]
   makeindex[name=not, title=Notações]
letlettergrouptextbf

begin{document}

My first paragraphldots

index[std]{premier niveau}
index[std]{niveau!1@premier}
index[std]{niveau!2@deuxième}
index[std]{niveau!1@premier!1@premier}
index[std]{niveau!1@premier!2@deuxième}
index[std]{étrangères}
index[std]{Ça va}
index[std]{À quelle}

index[not]{premier niveau}
index[not]{niveau!1@premier}
index[not]{niveau!2@deuxième}
index[not]{niveau!1@premier!1@premier}
index[not]{niveau!1@premier!2@deuxième}
index[not]{étrangères}
index[not]{Ça va}
index[not]{À quelle}

printindex[std]
printindex[not]

end{document}

(markup-index :open  "begin{theindex}~n"
    :close "~n~nend{theindex}~n"
    :tree)

(markup-indexentry :open "~nitem " :close "" :depth 0)
(markup-indexentry :open "~n  subitem " :close "" :depth 1)
(markup-indexentry :open "~n    subsubitem " :close "" :depth 2)
(markup-locclass-list :open "dotfill " :sep ", " :close "")
(markup-locref-list   :sep ", ")
