Project doesn't seem to run properly on MacOS

[Frituurpanda]

Per documentation I've set the BURPHOME variable but it doesn't seem to do anything on a Burpsuite MacOS installation.

 ~/Desktop/seltzer   master  echo ${BURPHOME}
/Applications/Burp Suite Professional.app
 ~/Desktop/seltzer   master  sudo sh bin/seltzer.sh -t target.txt

[2020-10-05 22:06:25 CEST][seltzer] BURPHOME is not set
[2020-10-05 22:06:25 CEST][seltzer] please set BURPHOME to your Burp Suite installation directory (e.x. export BURPHOME=/home/myuser/BurpSuite)
[2020-10-05 22:06:25 CEST][seltzer] exiting

 ✘  ~/Desktop/seltzer   master 

Looking at seltzer.sh, this could probably work with just the standalone Burpsuite jar. is There any obvious set I'm missing here?
