Dear respected,
As per the description, I understand your demand to have a developed usage with Microsoft Copilot. In this situation, we suggest you post a new thread in the related Copilot Community: Copilot for Microsoft 365 - Microsoft Community Hub
Please accept my Apologies for redirecting you to other channel as the moderators in this community mainly focus on out-of-box features in Microsoft 365 Office and Word app and have limited resources or experience to Microsoft Copilot feature updates, and to make sure you get the fast and appropriate assistance, we requested for it.
Meanwhile, we will still make sure to keep your thread open and welcome other community members or MVPs to share their ideas and experience about making a video with work instructions via Copilot.
Let me know if I made any misunderstanding or there have anything else I can do for you. Appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
Mia
