Quest to make AWS S3 work with InvoiceNinja

Round two.
I’ve tried this before without success. If anybody achieved this, please share how.
Seems like Ninja ignores AWS settings. There is 0 output about AWS config in logs.

Documentation I use for config:

#AWS S3 config in .env file
AWS_ACCESS_KEY_ID=s3_compatible_key
AWS_SECRET_ACCESS_KEY=a_long_and_glorious_key
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=some_bucket_name
AWS_URL=https://endpoint.com
AWS_ENDPOINT=https://endpoint.com/
FILESYSTEM_DRIVER=s3
#FILESYSTEM_DISK=s3

Setting up all the AWS_* variables didn’t do a thing.
So I tried changing the FILESYSTEM_DRIVER to s3 - nothing happend.
Setting up FILESYSTEM_DISK to s3 - didn’t change anything.

I could upload documents with 0 issues and there is no complains in logs. Running in debug.
