How to transfer precomputed mogodb index to another machine?

I have a local mongodb database that i want to transfer to a free tier aws ec2 t3.micro instance. The problem is that one collection in the db is a bit larger(1.2 GB, 24M docs), so there is no way i can index it locally on the dinky little aws machine. **I have the storage space but don't have the compute (ram and cpu) to create a index.** I tried transfering db with indexes via **mongodump** and **mongorestore**, but it doesn't look like it actually transfers precomputed indexes. mongorestore hangs the entire ssh session when restoring the particular large index (waited for hours)
