making a slash command (example):

[UCYT5040]

@bot.slash()
async def ping(ctx): #or whatever you need for a slash command#
""""description""""
ctx.send("Pong!")

what you can add for slash commands (+ examples) after defining the function:

#choices, makes a choice
Choice=["foo", "bar"]
#integer, makes sure inputted text is an integer
Int=""
#float, makes sure inputted text is a float
Float=""
#boolean, like a choice command, but it can only be True or False
Bool=[]
#string, allows the user to type smt
Str=""

#and the required, which is added after one of the above optionally
Rqd=Bool

example

@bot.slash()
async def echo(ctx):
Str="", Rqd=True
ctx.send(Str)

options will have to be placed in the @bot.slash decorator, like @bot.slash(options=[OptionTypes.String(name="foo", description="bar")])
