We would like to ask if it is possible to share a project between two "groups" or "communities" with different URLs (i.e. xxxx@atlassian. net and yyyy@atlassian.net). We are two companies (each owner of a group) that participate in the same project in a joint venture. One of the companies has already created a group with a specific configuration and some already registered tasks that we would like to share, is there a quick and easy way to do this? Thank you very much!
