[Gmsh] How can I name boundaries in GMSH?

How can I name boundaries in GMSH? Is there a way to do this in the GUI or do I have to edit the file?

More context: I'm trying to export a GMSH mesh in the SU2 file format, and I succeeded in that. But I need to define the boundary conditions (the object and farfield) in order to actually run the CFD simulations. How can I do this? Thanks for your help!

Modules -> Geometry -> Physical groups -> Add -> Surface

And you get entry field for name (see attached screenshot). IIRC older versions do not have this capability and you have to edit file.

OK, thanks!
