You will have separate Miro boards for each.
You'll manage an Client Miro board for your Client and an Internal Miro board for collaborating with your Creatives. Be sure to share each board with the appropriate people. Your Creatives may have access to the Client Miro board. If they do, make sure they can view only. The Client will not have access to the Internal Miro board.
The Client Miro board allows your Client to view deliverables and provide you with feedback.
The Internal Miro board for your Creatives will be a place where you can share mood boards, research, assets, and links with your Creatives. This is also a space where you can provide them with detailed feedback when they upload their deliverables.
