Tourist visa for minors traveling without both parents

Hello everyone, I have 2 minor sisters traveling without both parents through Emirates. On the website it says the kids should be linked with the parents when asking for a visa, however, the parents will be traveling from a different country therefore it’s not possible to join them with the kids because the reservations are different.

Can someone please advise me on how to proceed, if you could drop an email address of an entity who would be able to assist me please do so

Thank you
