Can you help with making an activity diagram for the below.

The IT personnel want to manage user accounts (create/modify/delete) and configure integration with other tools.

The user has root access to LMS, thus the admin module.

System changes are successfully saved and reflected within the LMS.

The user navigates to the "Administration" in LMS.

The user selects "User Management"

LMS prompts to create/modify/delete a user.

The user selects their choice.

LMS displays a form for the required information.

The user completes the applicable fields and submits the form.

LMS actions the entered information, updating the users accordingly.

2a. The user selects "DBMS"

2a1. LMS display configuration settings (eg DBMS SQL GUI).

2a2. The user makes necessary changes (eg API credentials, data transmission protocols, DNS details) and saves changes.

2a3. LMS validates the entered information connecting to external modules where applicable.

2a4. Returns to step 1.
