How to output a multiline message in the dap configuration callback?

[shmerl]

I'm trying to add such kind of dap config to attach to a process:

dap.configurations.c = {
  {
    name = "Select and attach to process",
    type = "cppdbg",
    request = "attach",
    processId = function()
      print("Set 'echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope' (reset it to 1 after you are done).")
      print("Press any key when ready...")
      vim.fn.getchar()

      local name = vim.fn.input('Executable name (filter): ')
      return require("dap.utils").pick_process({ filter = name })
    end,
    program = function()
      return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/', 'file')
    end,
    cwd = '${workspaceFolder}',
    setupCommands = {  
      { 
        text = '-enable-pretty-printing',
        description =  'enable pretty printing',
        ignoreFailures = false 
      }
    }
  }
}

Basically, the issue is that I want to see it printing such prompt in the status line before selecting the process

Set 'echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope' (reset it to 1 after you are done).
Press any key when ready...

But it ends up printing only the last one (i.e.

Press any key when ready...

Why does that happen and how can it be done to see multiple lines?

Thanks!
