Trying to send message to channel when command is executed discord.py

Question

Im trying to have this code automatically send a message in chat when someone executes it.

This code is to rename a channel, but the process may take a few mins and therefore id like to send a message right after the cmd is executed to tell the users to wait. any help would be appreciated.

    import functions as func
    from commands.base import Cmd
    
    async def execute(ctx, params):
        params_str = ctx['clean_paramstr']
        guild = ctx['guild']
        author = ctx['message'].author
    
        new_name = params_str.replace('\n', ' ')  # Can't have newlines in channel name.
        new_name = new_name.strip()
        if new_name:
            return await func.custom_name(guild, ctx['voice_channel'], author, new_name)
        else:
            return False, ("You need to specify a new name for this channel, e.g. '{0}name <new name>'.\n"
                           "Run '{0}help template' for a full list of variables you can use like "
                           "`@@game_name@@`, `@@creator@@` and `@@num_others@@`.".format(ctx['print_prefix']))
    
    
    command = Cmd(
        execute=execute,
        params_required=1,
        gold_required=True,
        admin_required=False,
        voice_required=True,
        creator_only=True,
    )
