[Tkinter] Choose from dropdown list and then do something?

[Selfiatus1]

Hi, there is an error with my if function... It just woun't write to the document when I press the button "Generate".
I only want to write to a document, a word that is based on the dropdown list, when I press the button "Generate"?
How should I code that?

import tkinter as tk
  
from docx import Document
  
HEIGHT = 500
WIDTH = 600
  
root = tk.Tk()
root.title("Generator")
canvas = tk.Canvas(root, height=HEIGHT, width=WIDTH)
canvas.pack()
  
background_image = tk.PhotoImage(file='bg123.png')
background_label = tk.Label(root, image=background_image)
background_label.place(x=-6, y=-6)
  
#dropdown part
# Create a Tkinter variable
tkvar = tk.StringVar(root)
choices = { 'broker','consultant','recruit'}
tkvar.set('broker') # set the default option
popupMenu = tk.OptionMenu(root, tkvar, *choices)
popupMenu.place(x=260,y=95)
  
def helloCallBack():
   
   if tkvar == 'broker':
      document = Document()
      document.add_heading("broker")
      document.save('0034.docx')
  
button = tk.Button(text="Generate", font=40, command=helloCallBack)
button.place(x=230, y=380)
  
root.mainloop()
