[SKYBLOCK 3] I can't /is fixhome

Greetings, I can't do /is fixhome . Yes, i am aware that i am not the leader of the island but the island leader has never been online for the past 1 year (The owner is Iman909danial ) i have tried to contact him, sadly he's unreachable and now i can't do /is home and i just could not leave the island and create a new one myself as I have worked super hard on it for the past few months. Is there anyway the server could make me the leader of this island as the current owner (Iman909danial) has never been online for almost a year? Thank you.

Here is my island's coordinate XYZ: 4344 / 18 / 2360

 

I don't know if anyone can help you. I can't say 100% sure but I just don't think it's possible.
This is my thought on the situation, do not take it as a final note.
