Make Requires Connected App, but Salesforce Now Uses External Client App (ECA)

Hi all,

It looks like Salesforce has changed the way Connected Apps are configured, now referring to them as External Client Apps (ECA). However, Make (Integromat) still requires a traditional Connected App setup for OAuth authentication.

Has anyone successfully connected Make to Salesforce using the new ECA structure, or is there a workaround to still create a classic Connected App? The option for Connected App is no longer available, and I am using a Dev Org, so I cannot open a case with Salesforce.

Any advice or recommendations would be greatly appreciated.

Thanks in advance!
