You can display the ACF button group type field via post meta block using the Combo Blocks plugin. This article will help you to display the ACF File field via post meta block.
To begin, insert a “Post Meta” block.
Insert the ACF button group type Meta field key into the Meta Key Field. [Note. I am using the ACF Plugin to set a post meta value].
Now choose the ACF button group type as the meta key type.
Here you will get some meta keys and values. Use one of them to display the meta value.
