Kotlin Android to Multi Platform

I have an Android Studio project written in kotlin and I used Jetpack Compose. I wrote it for Android and it is available in Play Store. It is downloaded 8 times till now. I want to support ios and desktop. Because I have not started my project as kotlin multi platform support, now it is something hard for me to support ios and desktop. I want to support ios and in a virtual machine I want to debug using ADB. I know the steps to do this but because I have not done this before, I feel in pain. I have not started this migration or extension yet. Is there anybody who has already made such thing? Feel free to ask questions to me, I will be transparent and I will answer with my best. Thanks.
