There are going to be a lot of “it depends” in regard to your question. If they have opened the link previously, then it will not work. They can create a new link and send that to you to use. Once the link has been opened, it cannot be opened again.
Also if the part after /map/ is a very long code, then it is likely that link has already been opened. If it is a shorter hashed code, then as long as no one else has not opened that link previously, you should be good to use the link.
Also, there may be a time limit on opening the link. If you want to provide more specific information such as usernames or the link that was provided to you, please feel free to contact us at firstname.lastname@example.org and we can look more into the account.
