            <item name="config" xsi:type="array">
                <item name="dataType" xsi:type="string">text</item>

        <settings>
            <validation>
                <rule name="required-entry" xsi:type="boolean">true</rule>
            </validation>
        </settings>
    </field>

Saved in database

test  <a href="{{config path='web/secure/base_url'}}lean-office">link </a>

When i call then this in the template, the config path isn't replace.

<div class="ss-booklets-mea-desc"><?= $meaBooklet->getDescription(); ?></div>

So as I'm getting this in front with the config path being not replaced

<a href="{{config path='web/secure/base_url'}}lean-office">lien </a>

The same thing in a cms block is fully replaced.

So...does magento only make this replacement for native cms block ? Is there some king of process method to call to make this replacement on my own code too ? I was hoping to avoid to use a replace method on the string return.
