Hello @Alexis Pejouan ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
This is expected as you are trying to access the folder via an “admin share” which is indicated by “c$”. To give access to regular users, you simply need to create a regular file share for \myserver\myfolder.
Just sharing an example guide for your help and understanding here
