How to solve error mail as attachement of a document within a business workspace.

We are using SAP FIORI and we can open the linked Business Workspace, but within the business workspace, it is not possible to mail a document as attachement. The following error is there.

If we follow the instructions then everything is already installed, OpenText Content server browser Web Extension is installed (other version).

When I open the business workspace in the edge browser then there is no problem.

but the SAP fiori is working with Edge Chromium Based.

We are working with the SAP Business Client 8.00 and we work with content server CE 22.1.

Does anyone knows how we can solve this?
