How to make the discord.py bot write that he has no rights?

Question

Python

I am writing a bot for discord, for the test I created a command that gives a role to the user, and added the "command_error" event to it.

As planned, the bot will simply write that it does not have rights, but alas, it does not write this :s
I'm worried about this for a very long time , I look through the documentation of both discord and python itself a million times in search of an answer.

As a result, I turn to connoisseurs)

Code:

@Bot.command()
async def rtest(ctx, *, member = discord.Member, role = discord.Role):
  roll = discord.utils.get(ctx.guild.roles, id = role.id)

  await member.add_roles(roll)
  await ctx.send("+")

@rtest.error
async def rtest_error(ctx, error):
    if isinstance(error, commands.BotMissingPermissions):
        await ctx.send("I don't have sufficient permissions!")
    else:
        pass

I would be grateful for any help and answer!

Well for starters

async def rtest(ctx, *, member = discord.Member, role = discord.Role):

Not "=" but ":". This is a type hint , not a default value.
discord.py itself will convert the specified parameters into Member and Role objects.
So in theory it will be enough to write

await member.add_roles(role)
  await ctx.send("+")
