How to reference/create parent block's dynamic ID G-Blocks

I’d like to create a BS accordion block. The inner blocks would require a reference to the outermost parent wrapper and also to the ID within it’s own sibling div. The outermost parent wrapper would have to have a unique ID in case multiple accordions are one page. I know how to construct the HTML and create the inner blocks to populate. Does anyone know how I can assign/get a dynam ID placed on the parent block? I’ve done this before with posts using their unique slug or ID but is there anything like that for G-blocks? -Thanks :grinning:
