Currently, I am involved in a project that utilizes a sub-domain under a parent domain called "my-project.parent.com", which unfortunately I do not have access to. Additionally, there is another project operating under the main domain "parent.com" with the sub-domain "other-project.parent.com". I am faced with the challenge of sharing cookies containing specific data from my project with the "Other-project". Despite trying various solutions, I have come to realize that most of them require me to access the parent domain project, which is something I am unable to do as I only have access to "my-project".
