How can Post Meta Key's be used anywhere?

Im using fusion builder (Avada) to build page templates. I want to use the button element to display the ‘phone’ meta delail into a button. I’m trying to use the shortcode tel:[gd_post_meta key=”phone” show=”value”] as the link which isnt working.
Is there a way to just output the relevant meta detail, or Is there another hook I should be using?

It would also be very handy if the meta detail can be placed anywhere within text or elements.

For example. The relevant post meta for address, email or even a keyword could be placed within a paragraph of text? or placed across specific page templates?

Is this possible?

This is the fusion button element code:
[fusion_button link=”tel:[gd_post_meta key=’phone’ show=’value’]” text_transform=”” title=”Test” target=”_self” link_attributes=”” alignment=”” modal=”” hide_on_mobile=”small-visibility,medium-visibility,large-visibility” class=”” id=”” color=”default” button_gradient_top_color=”” button_gradient_bottom_color=”” button_gradient_top_color_hover=”” button_gradient_bottom_color_hover=”” accent_color=”” accent_hover_color=”” type=”” bevel_color=”” border_width=”” border_radius=”” border_color=”” border_hover_color=”” size=”” stretch=”default” icon=”” icon_position=”left” icon_divider=”no” animation_type=”” animation_direction=”left” animation_speed=”0.3″ animation_offset=”” /]
