Issue Installing MMS Connector for Capella on Eclipse 6.1 and 7.0

[mcalveiro]

I have been trying to install the "MMS Connector for Capella" add-on on both Eclipse versions 6.1 and 7.0, which I currently use. However, I keep encountering the following error:
Cannot complete the install because one or more required items could not be found.
Software being installed: MMS Connector for Capella Feature 1.0.0.202009011549 (com.thalesgroup.mde.openmbee.connector.mms.feature.feature.group 1.0.0.202009011549)
Missing requirement: OpenMBEE MMS Connector - Sirius Converter 1.0.0.202009011549 (com.thalesgroup.mde.openmbee.connector.mms.sirius 1.0.0.202009011549) requires 'osgi.bundle; org.eclipse.sirius [6.0.0,7.0.0)' but it could not be found
Cannot satisfy dependency:
From: MMS Connector for Capella Feature 1.0.0.202009011549 (com.thalesgroup.mde.openmbee.connector.mms.feature.feature.group 1.0.0.202009011549)
To: org.eclipse.equinox.p2.iu; com.thalesgroup.mde.openmbee.connector.mms.sirius [1.0.0.202009011549,1.0.0.202009011549]

It seems that the required version of org.eclipse.sirius (between 6.0.0 and 7.0.0) cannot be found, which is preventing the installation from completing. This issue persists in both Eclipse 6.1 and 7.0 environments.

Could you please advise on how to resolve this issue? Is there a specific version of Sirius or any additional steps that I need to take to successfully install the add-on?
Thank you for your assistance.

Best regards,
Miguel
