Not sure about your actual problem. But, it's working fine. Just follow this step :
{
products (
filter: {
price: {
gt: "40"
lt: "50"
}
}
)
{
items {
name
}
}
}
Copy this above query at left side (In query variable part) and just execute "Execute-Query" button (Ctrl + Enter)

You are on the right track but you can easily view Documentation when you click on Docs on the right top corner.
See screenshot with an example for the Category Query and the Documentation in the right sidebar.
