In principle, it should be possible to access all data stored in the Google Business Account. It works with reviews. 
It has menus. Others have offers, posts, and images.
Distributing the data to the individual widgets would then be targeted.
For business hours, it has the advantage that recurring data such as holidays, etc., no longer have to be entered manually. Therefore, this app is only of limited use for me.
