Burp Suite Basics: Intruder - Stuck on missing password.txt

Hello community,

I'm stuck in lab https://mercedes-benz.immersivelabs.online/v2/labs/burp-basics-intruder/series/burp-suite.

The attack to carry out is about a brute-force guess on mfogg1's password using the intruder.

The briefing states:

Brute force the login page using the password.txt list against the user mfogg1.

I'm missing that password.txt file, where the heck is it?

I carried out an intruder attack (Cluster bomb) using well known passwords from

/usr/share/wordlists/metasploit/burnet_top_1024.txt

without success. Even worse, testing those 200 attacks (there are only 200 passwords in that file), tooks quite a considerable time.

I must have missed something about the location of that obscure password.txt file. 
I'm stuck.

Perhaps someone can shed a light on this.
Thanks in advance,
Wolfgang
