LaTeX Texmaker - Creating a separate file for glossary

I am currently finalizing my thesis and I am know trying to create a separate file in which I store all the glossary entries. I found exactly the same question here but it does not seem to work. I am new to StackExchange and therefore do not feature enough reputation to comment. So thats why I am asking again.

documentclass{article} 

usepackage{glossaries}
makeglossaries

loadglsentries{begrippen.tex}
begin{document}

% First part of thesis

section{example}
Here is an example provided by another stackexchange question, 
gls{foobar} is a strange animal

gls{foo} is another strange animal


% Bibliography
newpage
bibliographystyle{apacite}
bibliography{refference}

% Glossary
newpage
glsaddall
printglossaries

end{document}

And the other file with the entries: (saved as “begrippen.tex)

newglossaryentry{foobar}{%
  name={Foobar},
  description={A strange animal, not to be confused with gls{foo}}
}

newglossaryentry{foo}{%
  name={Foo},
  description={A strange animal, not to be confused with gls{foobar}}
}

When I run the thesis The gls{foo} and gls{foobar} are both shown in the text, but there is no sign of the printed glossary.

Does anyone have any suggetions?

Thanks!
