Simple way to install app on multiple quest 2 devices

Hi there,
I am currently developing a VR experience for a museum and they will want to have several stations for visitors to use in the museum for the exhibition.
I'm working with unreal engine, and I was wondering if there would be an easy way for the museum to install the app onto multiple headsets. Would they need to create as many Facebook accounts as they have headsets?
Is Sidequest recommended or can I just copy files over onto the headsets? Right now I'm just launching the app from UE4 and it works fine but they won't have ue4 installed on their end.
Just trying to figure out the easiest way for them to install the app once it's ready.

Many thanks,
Pascal
