You need to change this line in your ui_component file

<item name="toggle_button" xsi:type="boolean">false</item>

with this

<item name="toggle_button" xsi:type="boolean">true</item>

After changing this value from false to true please run below commands.

php bin/magento cache:clean && php bin/magento cache:flush

Hope this will help you!
