Upcoming breaking slack API changes

I bit ago I got an email saying slackcat will stop working in 2025, and that nobody can add slackcat to a workspace as of a month ago

Your usage of files.upload requires attention for: Slackcat

Hello $name,

We want to inform you of two important dates related to upcoming changes to support for the files.upload web API method that affect your Slackcat app.

May 8, 2024
Any new applications created on or after this date will be prevented from invoking the files.upload API.

March 11, 2025
Support for the files.upload API will be discontinued.

To prepare for this change, we recommend migrating away from files.upload and instead using the combination of files.getUploadURLExternal and files.completeUploadExternal. More information on how to use these two APIs together can be found on our Uploading files documentation. You can also leverage Slack’s SDKs to help you transition to this new way of uploading files by visiting our api.slack page.

I don't know go at all, but if nobody fixes this before it breaks, I may take a stab at it
