Unable to get "Guest users work with shared semantic models in own tenants" to work correctly

Hi,

We have successfully set up guest access as far as the guests are able to access the workspace and see the report and the semantic model.

However, they are unable to see the semantic model in their own tenant and are unable to build reports on it. 

We have tried to follow the instructions here: Power BI in-place semantic model sharing with guest users in external organizations (preview) - Power BI | Microsoft Learn but they are rather confusing and there doesn't seem to be one checklist that can be applied.

We have set these settings:

* "External data sharing (preview)" on for the guest group
* "Guest users can brows and access Microsoft Fabric" on for the guest group
* "Users can accept external data shares (Preview)" on for the guest group
* "Allow specific users to turn on external data sharing" (begränsad till admin - on for administrators
* "Guest users can work with shared semantic models in their own tenants" (Enabled)

The guest user has done the following in Power BI Desktop, but no semantic models show up under "external orgs"

1. Select the checkbox next to the DirectQuery for PBI semantic models and AS option

2. Select the checkbox next to the Connect to external semantic models shared with me option

On the actual semantic model that we have shared in the workspace I have made sure that "External sharing" is turned on.

Can someone provide a simple bullet-point checklist of what we need to have in place?
