discord.py 1vs1 game - accept invite function

Question

Im making a 1vs1 game that sends invite to user and awaits for accept. Here is my code:

global hasRun
hasRun = False
@client.command()
async def accept(ctx):
    global hasRun
    hasRun = True

@client.command() 
async def fight(ctx, user: discord.Member):
    await ctx.send('sending invite to user')
    await user.send('press `/accept` to start the game')
    await ctx.send('waiting for accept..')
    global hasRun
    if hasRun == True:
      await ctx.send("game started")

Code doesnt drop any error but it just doesnt work. Any idea where the fault lies?
