How to show tags_title in template

[oschibsted]

Hello!

I am running Joomla version 3.9.4

I have a menu item of type "Tagged Items" on my site, that lists all articles related to ONE tag. I want to show this tag in the header of index.php when in one of these menu items .

I managed to get this to work with article-titles with some custom php-code in index.php, but i cannot get it to work with this tag-title.

This is the title i want to include in the header (from components/com_tags/views/tag/tmpl/default.php):

<h2>
<?php echo JHtml::_('content.prepare', $this->tags_title, '', 'com_tag.tag'); ?>
</h2>

Is it possible to include this title where i want it in index.php? I have tried to find a solution for this for days, but i cannot figure it out. Any help is very much appreciated.
