update/reload choices in slash command on use PYTHON nextcord

[Lxodles]

so I was creating discord bot with db..

so i have slash command that creates data for DB then giving him id (ofc i need something here to update the choices for second slash command)
and a slash command that removes data from DB using id

i saw something about restarting the script.. heres some of those ideas

os.execv(sys.argv[0], sys.argv)
--OSError: [Errno 8] Exec format error
os.execv(sys.executable, ['python3'] + sys.argv)
--this looked promissing but the bot will stop functioning normally (eg. not answering to commands)

i searched more and i found you can just remove it then add it back

@client.command(name='aideletecommands', aliases=['aidc'])
@commands.has_any_role('Owner')
async def delete_commands(ctx):
    client.tree.clear_commands(guild=None)
    await client.tree.sync()
    await ctx.send('Commands deleted.')

--this doesnt work for me and gives me an error: 'Bot' object has no attribute 'tree'

i even found module dslash but PROJECT IS NO LONGER MAINTAINED and can be considered unstable.

im already running out of idea..
so does anyone know any way? anyway any repsonses are welcome here and thank you for your time
have a great day :0
