play video links in lightbox

HI
I have 2 text links in the page below that wanted to open in a lightbox instead of a separate tab opening in Vimeo or YouTube. I had these links:

<a class="mfp-iframe lightbox-added" href="https://youtu.be/875DFvXB630" target="_blank" rel="noopener">Om De Kreatives Kontor</a>
<a class="mfp-iframe lightbox-added" href="https://vimeo.com/315667049" target="_blank" rel="noopener">Samarbejde mellem CULINN og Turning Tables: Mød Abyan</a>

but could not get the lightbox to open.

Now I tried the links in a button element, and the Vimeo link works fine but the YouTube one doesn’t.
the YouTube button link is:
[av_button label=' SE VIDEO: Om De Kreatives Kontor' link='manually,https://youtu.be/875DFvXB630?iframe=true' class='open-popup-link' link_target='' size='medium' position='left' label_display='' icon_select='yes' icon='ue897' font='entypo-fontello' color='dark' custom_bg='#444444' custom_font='#ffffff' av_uid='av-3x1gt6' admin_preview_bg='']

I looked at this thread https://kriesi.at/support/topic/open-lightbox-with-an-iframe/#post-710141 and tried adding ?iframe=true” class=”open-popup-link” but that didn’t work – the lightbox opens but the video doesn’t play.
Can you help me with this?
thanks
Nancy
