Update theme after Embed On Your Website

Hello. Currently we are following the documentation instructions here with Vue js

I see I can add a value theme when embed featurebase in OnMounted, but on the web we have a button to toggle dark mode. When changing this value, the theme value also needs to be changed for Featurebase to turn on/off dark mode in iframe. Is there any way I can edit that value? Even if I reuse the init code every time I toggle dark mode, Featurebase still won't re-init
