graphically browse s-expression output from antlr4

Question

Is there a way to take the S-Expression output from Antlr4 and display it graphically as a treeview in Windows 10?

here's my grammar file for antlr4:

https://github.com/antlr/grammars-v4/blob/master/vhdl/vhdl.g4

here's my vhdl program to parse with antrl4:

entity testbench is

end entity;

architecture beh of testbench is
begin

end architecture;

Here's my S-Expression Output from Antlr4 for the vhdl file:

(design_file (design_unit context_clause (library_unit (primary_unit 
(entity_declaration entity 
(identifier testbench) is entity_header entity_declarative_part end entity ;))))
(design_unit context_clause (library_unit 
(secondary_unit (architecture_body architecture (identifier beh) of 
(identifier testbench) is architecture_declarative_part 
begin architecture_statement_part end architecture ;)))) <EOF>)

I want to see the s-expression output from antlr in a treeview with collapable nodes, something like this:

Is there a windows 10 program for graphically browsing the s-expressions output of antrl4 as a graphical treeview?

Ideally I want something that reads the antrl s-expressions generated by -tree flag, and the tokens list generated by -tokens flag, and merges them together for display in a GUI treeview so that when i click on a node of the s-expression in the tree and i get the information in the token file as well...

For Java target, use Trees.inspect(tree, parser) . It'll pop up a window with the tree view. Or use Intellij/jetbrains plugin
