go back to itunes from music and tv app in windows

I have been happily using iTunes on windows for many years. Today I wondered how I could play Apple TV+ on my windows 10 pc. I saw you could either do via a browser or download the apple tv preview app from windows store. I decided for convenience to do the latter. What a mistake that was. I opened it and it’s basically rendered my iTunes useless as it’s only showing audiobooks and podcasts now. By installing and opening the new app it’s taken over. I have lots of purchased music and iTunes Match music and lost it all I thought. Thankfully by downloading the Apple Music app from windows store I could then see it all now in here

my question is , how can I get back to iTunes so I can see all my music and purchased films/shows in here? I only download the tv app to watch Apple TV+ content and never expected this unpleasant side effect

many thanks,

Wayne
