Magento2.4 System Integration not being activated

I want to connect Magento2 with Zoho inventory. So, I have used Cartrover service for this. As per Cartrover docs, I have tried to connect but Magento System Integration not being activated.
Cartrover Magento steps:

  • Within the Magento admin section, go to System > Extensions >
    Integrations

  • Click Add New Integration and then enter the following fields. The
    URL entries must match exactly!

  • Name: CartRover (or another name that lets you know who this
    connection is for)

  • Email: Callback URL: https://app.cartrover.com/call_back/Magento2

  • Identity link URL: https://app.cartrover.com/

  • Click API on the left-hand side of the screen. Select the Sales,
    Catalog, Carts, and Stores->Settings->Configuration->Inventory

  • Click Save at the top of the screen.

  • Click the Activate link on the new line labeled CartRover

  • Click Allow in the upper right.

  • Close the CartRover window that pops up

  • Confirm the connection

But click on allow button, Magento showing the below message and integration not activated:

Integration ‘CartRover’ has been sent for activation.

Magento version: 2.4.2
