I have been using the same commands that you have posted here for some releases. However, they stopped working in one of the 2024 releases and are not working in 2025R1:
cmds = '''
DS.Graphics.GfxUtility.Legend.ApplyLegendStyle("{}")
'''.format(guid)
ExtAPI.Application.ScriptByName("jscript").ExecuteCommand(cmds)
What commands can I use in 2025R1? Python is of course preferred.
