Inject Shortcode in Content Slider

Hi

I’d like to be able to inject shortcode into the php file that is responsible for the Content Slider widget.

The shortcode is for an accordion with an embedded button.

Where would I inject this shortcode into the relevant php file?

Example shortcode:

[av_toggle_container initial='0' mode='accordion' sort='' styling='' colors='' font_color='' background_color='' border_color='' custom_class='' av_uid='av-1ejqh']
[av_toggle title='answer' tags='' av_uid='av-14crd']

answer goes here

[av_button label='Next Question' link='manually,#next' link_target='' size='large' position='left' label_display='' icon_select='yes' icon='ue832' font='entypo-fontello' color='custom' custom_bg='#313d8b' custom_font='#ffffff' av_uid='av-10ni5' custom_class='next-slide' admin_preview_bg='']

[/av_toggle]

[/av_toggle_container]

Kind ergards
