How do I link buddypress users to their profile?

Update: I just found this code from the creators on github and I’d imagine it will work, but I’m not sure where to add it:

<?php
// Add BuddyPress profile to sidebar. Should check if appwoo is active, or double profiles will show.
// Author: Scott Bolinger https://apppresser.com
add_action( 'appp_left_panel_before', 'ion_bp_profile', 99 );
function ion_bp_profile() {
	if( !is_user_logged_in() )
		return;
	$user         = wp_get_current_user();
	$display_name = isset( $user->display_name ) ? $user->display_name : '';
	$user_email   = isset( $user->user_email ) ? $user->user_email : '';
	$user_first   = isset( $user->user_firstname ) ? $user->user_firstname : '';
	$user_last    = isset( $user->user_lastname ) ? $user->user_lastname : '';
	$profile_link = bp_loggedin_user_domain( '/' );
	echo '<div class="item menu-profile">';
	if ( $user_email ) {
		echo '<a class="ajaxify" href="' . $profile_link . '">' . get_avatar( $user_email, 50 ) . '</a>';
	}
	if ( $user_first || $user_last ) {
		$name = $user_last;
		$name = $user_first ? $user_first .' '. $name : $name;
		echo '<h2 class="item-title"><a class="ajaxify" href="' . $profile_link . '">'. $name .'</a></h2>';
	} elseif ( $display_name ) {
		echo '<h2 class="item-title"><a class="ajaxify" href="' . $profile_link . '">@'. $display_name .'</a></h2>';
	}
	echo '<p>Welcome back!</p></div>';
}

The good people at Apppresser recently made an article on how to do this, and it’s much easier than initially thought. For anyone else encountering this issue, you simply place “me” as an arbitrary placeholder for your users. Read the full article here:
