Installation Steps
Subscribe via Microsoft AppSource, activate your tenant, configure Power BI, invite your team.
Follow these steps after you've completed the Prerequisites. The flow is: subscribe on AppSource, activate your tenant on the Vizlake landing page, configure Power BI, and invite your team.
Subscribe via Microsoft AppSource
Open the Mosaic listing on Microsoft AppSource
Click Get it now and choose Mosaic Standard or Mosaic Premium
Complete the purchase under your Microsoft 365 tenant's billing profile
After purchase, AppSource redirects you to the Vizlake activation page.
Activate your tenant
You arrive at the shared Vizlake activation page — the same landing experience used by AiDi. It recognises which Vizlake product you've purchased (Mosaic or AiDi) and provisions the right tenant for you.
Sign in with the Microsoft Entra account that has tenant administrator rights
Review the requested permissions:
Sign in and read your profile
Read Power BI content on behalf of the user (delegated, OBO flow)
Tick Consent on behalf of your organisation (strongly recommended — saves every user from a separate consent prompt later) and click Accept
The activation page provisions your Mosaic tenant and redirects you to the product
Tenant-wide admin consent at this step avoids per-user consent prompts later. If your organisation requires admin consent for any third-party app, see Azure App Registration → Tenant-wide admin consent.
Configure Power BI
Mosaic must be allowed to call your Power BI tenant on behalf of your users. Complete the Power BI Configuration section before inviting users.
Configure your LLM
Mosaic doesn't include AI inference - you bring your own LLM capacity. Connect Azure AI Foundry (recommended) or paste an API key from Anthropic / OpenAI. Until this step is done, the chat panel will show "AI not configured" and agent runs are blocked.
Onboard your team
Activate creates a personal workspace for the admin who signed in, with a "Getting Started" page. To work with others, create a shared workspace and invite teammates by email - see Accessing Mosaic.
Smoke-test before broad rollout
Before rolling Mosaic out to your whole BI team:
Sign in with a test user from your tenant
Confirm the test user can see the workspace they were invited to
Embed one Power BI report and confirm it renders under the test user's identity (Row-Level Security should hold - the user should only see what they could in Power BI directly)
Run a sample DAX query to confirm Power BI access is working end-to-end
What if something goes wrong?
