Not able to pledge Bharat Bond

I got the allotment for the recent Bharat Bond Series ( EBBETF0433) and I can view the same in the console

I am not able to pledge the same, since this is new scrip do we need to wait for few days or is it something that cannot be pledged even in future.

Thanks in Advance

This is currently not approved for pledging by the Clearing Corporation. Once it is, you will be able to pledge. The CC updates it’s list of approved securities each month. You can check list of all the approved securities here: Approved list of Securities at Zerodha. - Google Sheets
