alternative to admin-bro-upload-array?

[TheBeka]

Hi guys, I'm having a little problem with the library's upload feature. so basically here is my data model

{
...
data: [
{
fileUrl: [string], // list of strings
...
},
{
fileUrl: [string],
...
}
]
}

I need to be able to upload an array of files for each element in the array. I found this library but it's not for admin js instead for an old version of it. I really want to avoid downgrading. I think that there must be a way to do what I need but I can't find it anywhere.
even though this seems like a really useful feature
