Why does express.static work with app.use but not with app.get

In my server.ts file the line

app.get('/example', express.static('somefolder'));

gives me a 404, whereas

app.use('/example', express.static('somefolder'));

correctly serves the 'index.html' from 'somefolder' as a response to requests to 'myhost/example'.

According to the express documentation these should behave exactly the same in cases of GET requests. Why does one work and the other doesn't?
