I meant that you should execute the commands in the script in the current shell, like so:
Calling the script spawns a new shell process which ceases to exist when the script exits. You need to execute the commands in the context of the current shell, hence the use of dot opperator ".".

newgrp
NEWGRP(1) BSD General Commands Manual NEWGRP(1)NAME
newgrp -- change to a new group
SYNOPSIS
newgrp [-l] [group]
DESCRIPTION
The newgrp utility creates a new shell execution environment with modified real and effective group IDs.
The options are as follows:
-l Simulate a full login. The environment and umask are set to what would be expected if the user actually logged in again.
If the group operand is present, a new shell is started with the specified effective and real group IDs. The user will be prompted for a
password if they are not a member of the specified group.
Otherwise, the real, effective and supplementary group IDs are restored to those from the current user's password database entry.
EXIT STATUS
The newgrp utility attempts to start the shell regardless of whether group IDs were successfully changed.
If an error occurs and the shell cannot be started, newgrp exits >0. Otherwise, the exit status of newgrp is the exit status of the shell.
SEE ALSO csh(1), groups(1), login(1), sh(1), su(1), umask(1), group(5), passwd(5), environ(7)STANDARDS
The newgrp utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A newgrp utility appeared in Version 6 AT&T UNIX.
BUGS
Group passwords are inherently insecure as there is no way to stop users obtaining the crypted passwords from the group database. Their use
is discouraged.
