How to reduce the File storage size (delete profile image)

My file storage space is too small, so I can’t send files in chat.
I’m using Sendbird’s file storage for my profile images, and I’d like to move them to a different location.
How do I delete my existing profile images?
Will the files be automatically deleted if I change the URL of my profile images?
For example, my profile URL was previously stored in Sendbird’s file storage space, https://file-ap-x.sendbird.com/profile_images/~~~.jpg.
I want to save my profile images externally and change the profile URL to https://~~.cloud.net/images/~~~.jpg.
I wonder if this change will automatically delete the profile images stored in Sendbird’s storage.
If they aren’t deleted automatically, how can I delete them?

I found the following. It doesn’t answer whether deleting a profile image actually deletes the files internally.
It simply states, “Over time, your old profile image will become inaccessible.”
I’d like to know if deleting all profile images or updating them to a URL from a repository other than Sendbird’s server will reduce the file storage size.

# How do you remove the user’s profile image?

I uploaded the user’s profile image using profile_file. This automatically generated and populated profile_url.

My question is how do you remove the user’s profile image? Passing an empty string in profile_url works, but the file is actually still on Sendbird’s server (pasting the url in a browser still loads the photo). However, this is not ideal as I assume the file still counts against our storage limit.

Is there a way to reset profile_file and actually delete the file?
