Serving pgadmin4 from subdirectory (e.g. example.com/pgadmin4)

Is it possible to serve pgadmin4 from a subdirectory instead of at root
level? It's easy to serve at pgadmin.example.com - but how about at
example.com/pgadmin4 ? Is there any way to set a baseurl at the pgadmin
level?

It looks like two other routes are requested - /static/ and /browser/ -
that will break the app because they'll be requested at example.com/static/
instead of example.com/pgadmin4/static/ which is desired. It seems like as
long as other applications don't need these subdirectories then pgadmin4
can own them without impacting other services, but it's not a good
long-term solution. Then in nginx I can route /static/ and /browser/
directories at the root level to the pgadmin backend, but this is a hack.

Is there any way to serve pgadmin4 from a subdirectory or to change the
base_url that is used for the requests in the js/html?
