insufficient privilege: Not authorized

Hello everyone. I have the most poplular issue, but I don't understand how to solve it.

Two point of my issue

1)I can't create new schema in p*******trial/catalog

2) But I can create some table in existing NEO_30BK938A7DOYWS5MXEP12UONI schema

as a result in xsjs file I want to select data from created table like this:

$.response.contentType = "text/html";

var output = "Hello, " + $.session.getUsername() + " <br><br>";

var conn = $.db.getConnection();

var pstmt = conn.prepareStatement( "select * from NEO_30BK938A7DOYWS5MXEP12UONI.CREDITS" );

var rs = pstmt.executeQuery();

if (!rs.next()) {

$.response.setBody( "Failed to retrieve data" );

$.response.status = $.net.http.INTERNAL_SERVER_ERROR;

} else {

output = output + "This is the response from my SQL: " + rs.getString(1);

}

rs.close();

pstmt.close();

conn.close();

$.response.setBody(output);

But I just get  InternalError: dberror(Connection.prepareStatement): 258 - insufficient privilege: Not authorized at ptime/query/checker/query_check.cc:2422 (line 5 position 0 in /p1941403348trial/hanadb/test/hello.xsjs)

In my application I have this 3 files: .xsaccess .xsapp .xsjs

I don't understand should I create .xsprivileges and hdbrole file
