Hi @Verstappen Karen ,
According to my research and testing, you can try the follow steps:
1, First make sure that the account used has full control permissions for the video.
2, Add your whole company user to a group.
3, Open the video and then you can see the "Share" in the upper right corner. Click Share-->Manage access.
4, Then a dialog pops up, Click Advanced.
5, Click Grant Permissions to assign the appropriate permissions to the group.
