Discord slash commands do not support endless parameters/variadic options. The easiest solution would be to only allow a single member per command and make the user run it multiple times.
If you insist on using multiple members per command, you will need to use a workaround by creating a str argument, making the user put multiple mentions in there and then parse them. Here is an example using regular expressions:
import re
@client.tree.command()
@app_commands.describe(mentions='The members you want to get the joined date from; defaults to the user who uses the command')
async def joined(interaction: discord.Interaction, mentions: Optional[str]):
if not mentions:
members = [interaction.user]
else:
members = []
for user_id in re.findall(r"\d{17,19}", mentions):
member = interaction.guild.get_member(int(user_id))
if member:
members.append(member)
This requires Server Members privileged intent.
