Display custom data in my-account dashboard

Thanks @sharmadpk03
I’ve completed those steps, but I have not yet been able to get my function display results in the dashboard.

function fetch_member_id(){
	$current_user = wp_get_current_user();
	$current_user_id = $current_user->ID;
	global $wpdb;
	$result = $wpdb->get_results('SELECT meta_value FROM usermeta WHERE meta_key = \'random_number\' AND user_id = ' . $current_user->ID);
	foreach($result as $row){
		return 'Membership ID: '. $row->meta_value;		
	}
}

I’m trying to display a membership id in the user’s dashboard, but I get the following error in the dashboard tab
