I can list the commands with telescope_dap.commands({}) but selecting one does only run it without arguments. It fails e.g. for set_debug_level:
E5108: Error executing lua: /home/asn/.local/share/nvim/lazy/nvim-dap/lua/dap/log.lua:34: Log level must be one of (trace, debug, info, warn, error), got: "nil"
It actually would need to give another selection for the debug levels ...
