Sync messages from Slack to Teams and vice versa

Hello,

In my organization, we are using both Slack and Teams.

I would like to have one channel in Slack that is synced into Teams, where messages created in Slack will be created in Teams, and vice versa.

I tried SlackBridge, since this is a free app, but without success: It was installed succesfully into Slack and Teams as well, however, messages in one app is not transfered into the 2nd app.

Alternatively, I tried to sync using Workato, however, I didn't find a Microsoft Teams connector as a trigger (but only Workbot for Microsoft Teams).

What's the difference between Microsoft Teams connector and Workbot for Microsoft Teams connector?

Is there any recommended free app?
