Title

Missing Loading Indicator for Papermark Assistant Initialization

Description

Currently, after uploading a document to Papermark and activating the Papermark Assistant, a toast notification appears: "Papermark Assistant successfully activated." However, the user does not receive any feedback while the assistant is initializing, which could take a few seconds. This lack of feedback can cause confusion, as it isn't clear whether the assistant is loading or if something went wrong.

To enhance user experience, a loading indicator should be displayed during the initialization phase of the Papermark Assistant. This will provide a clear sense of progress, allowing the user to wait or perform other tasks until the assistant is ready.

Steps to Reproduce

1. Upload a document to Papermark.
2. Turn on the Papermark Assistant.
3. Observe the toast notification that appears, but no indication that the assistant is being loaded.

Expected Behavior

A loading indicator (e.g., spinner or progress bar) should be visible from the time the user activates the assistant until it is fully initialized, at which point the "successfully activated" toast can appear.

Additional Context

• The loading indicator should allow users to continue with other actions while waiting.
• Once the assistant is ready, the user can open the assistant screen.

This change will improve the user experience by providing visual feedback during the loading phase, reducing confusion.
