These pictures show the brackets supplied by Mianne with my 12'-by-8' table around 1999 - used to fasten the plywood top to the legs and beams. They came with the countersunk holes and screws.
I used a different approach for my 10'-by-5' table in 2014. I cut wood blocks (3-inches square by 1/2-inch thick and glued them to the underside of the tabletop plywood in the corners of the Mianne framework. The blocks locate the plywood within the framework but allow the plywood to be lifted off the table. This facilitates disassembly if the layout ever has to be transported to a new site.
