Autumn Error: Skipping existence check, make sure your S3 buckets exist!

[DezyNation]

I'm using Vultr and have created a bucket, let's say it mybucket
I want to use this bucket to store all of my media of my Revolt Chat's instance.
Also I can't create multiple buckets namely attachments, emojis, avatars, icons, backgrounds and banners because S3 bucket names must be unique in any particular region and many of these names have already been taken in all regions.

This is my .env config

# S3 Region
AUTUMN_S3_REGION=del1

# S3 Endpoint
AUTUMN_S3_ENDPOINT=https://mybucket.del1.vultrobjects.com

Is it possible to use only one custom bucket name ( mybucket )? If not what's the possible workaround?
PS: I can't use minio because I'm using an instance with very less storage (Only 100 GBs).
