How to configure custom filter for git grep?

Question

I am using mozilla/sops for encrypting and storing the secrets on git. They suggested a git diff filter to decrypt the data on git diff and it shows the actual diff of secret instead of diff of cipher-text.

I configured this git filter using following commands.

git config diff.sopsdiffer.textconv "sops --decrypt --config /dev/null"

and adjusted .gitattributes with *?.sops.yaml diff=sopsdiffer attributes.

This basically means for abc.sops.yaml file git diff will decrypt the file content and shows dif f of original secret.

Similarly, I want to use git grep to decrypt and search in the decrypted content. However it does not work.

I used following commands to configure git grep filter.

git config grep.sopsgrepper.textconv "sops --decrypt --config /dev/null | grep -"

and adjusted .gitattributes with *?.sops.yaml grep=sopsgrepper attributes.

I then tested it with git grep "secret_value".

Any help/hint would be appreciable. Thanks

Okay, I further probed into git-scm doc and realized there is is not grep filter driver for git. That means I cannot use the driver filter for git grep ...
