The collectGeometries function is really intended to operate on the result
of the queryCollection function - I'm not sure it's possible to pass it a
literal geometry. And if it is, the argument will need to be in correct
Filter XML syntax (ie GML-style geometry).
If the filter is just against a constant geometry value, this isn't really
cross-layer filtering. You can just use a plain Filter or CQL filter
expression.
