Try this one!!!

You need to use a Custom Configuration Profile with JSON payload to push bookmarks to Edge.

1. Log in to Jamf Pro.
2. Go to Computers → Configuration Profiles → New.
3. Add a name (e.g., Edge Bookmarks) and choose the scope (like "All Managed Macs" or a specific group).

Add the JSON payload

1. Select Custom Settings → Add.
2. Choose Application & Custom Settings → Add.
3. Select Upload JSON and add the following JSON configuration:

{
"com.microsoft.edge": {
"ManagedBookmarks": [
{
"name": "Company Portal",
"url": "https://companyportal.example.com"
},
{
"name": "Support Page",
"url": "https://support.example.com"
}
]
}
}
