I will be staying at a hotel near Graffenstaden train station for 3 days. But i need to travel to Strasbourg everyday. Would like to know what is the cheapest and fastest way to move between these two train stations.

I see there is a TER train every hour from Graffenstaden to Strasbourg and journey is just 7 mins.

I will be buying the 72hour solo ticket using the cts app but i am wondering if that ticket will allow me use the TER train or do i need a separate ticket to use the TER train?

thanks in advance.
