Filter Pop-up based on relationship

Question

Anyone able to get this working? I tried what Neeraja P suggested in sugarcrm filter on relative field - Dev Answers & Best Practices - DevClub - SugarClub so far not working. Here is the code I am adding to custom/Extension/modules/RTPOL_OLP/Ext/Vardefs/sugarfield_contacts_rtpol_olp_1contacts_ida.php 
 
 
$dictionary['RTPOL_OLP']['fields']['contacts_rtpol_olp_1contacts_ida']['filter_definition'] = [
 [
 'account_id' => '#accounts_rtpol_olp_1accounts_ida'
 ]
];

I am trying to filter Contacts based on Account, but getting this working will lead to other filters.

Do you have "links" in both side of the relationship? 
 I think the problem is the value that you use on the filter relate. 
 'filter_relate' => array(
 'accounts_rtpol_olp_1accounts_ida' => 'account_id'
), 
 
 In my code "'intermediary_account_id'" is a link created on the custom module side. 
 I suggested that post because for me it was fundamental to understand and create the links on both side of the modules. 
 'filter_relate' => array(
	'intermediary_account_id' => 'account_id'
),
