Custom module tab don't behave as tab

Developing for Dolibarr
1

Hi all
Newby here
I made module for my business needs following wiki and added a tab in thirdparty card.
Tab link is ok and when i press link my page is working
problem is it does not behave as tab but replaces the thirdparty screen with my own page.
What i am missing?
Thanks in advance

Hello,
It would be easier to answer if you post here the new tab description from your module descriptor, and what dolibarr version number you use.

version 18.0.3
tab

$this->tabs = array();

$this->tabs[] = array('data'=>'thirdparty:+tabname1:tab1:test@test:1:/test/lib/testtab.php?id=__ID__');
