I’d like to embed Google business posts on the website as notification of holiday or some events,
like using CMS.
Hi @Hiroki_MINAMINO and welcome aboard 
A huge thank you for adding your idea to the Wishlist!
We see how useful the Google Business post option might be for our users, so we’ll try our best to consider it for the future updates. I’ll keep you in the loop 
Hi,
I’ve been searching around the internet for a widget to show my Google Business Profile Post/Updates on my website. I found that feature in only two tools - embedsocial, SociableKIT.
I searched on your widget listing, and there was no such widget, but our office uses your review widgets for our websites. It’s easy and the best styling. It would be new idea for widget.
Thanks
Best Regards,
Umair Ilyas
Welcome to the Community, @Umair_Ilyas 
You’re right, we don’t have such an app in our catalog, but a similar idea is already on the Wishlist. I’ve merged your comment with it.
We can’t promise that this app will be definitely released. However, if more users support this request, we’ll try to think it over in the future
