Slack deprecating files.upload


we use the Metabase App in Slack for delivery of Dashboard Subscriptions. Last week we got a mail from Slack informing that the files.upload Method (which Metabase App is apparently using?) will be deprecated:

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 Metabase 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 guess this is something the Metabase team will have to take care of?
