what is the checkpoint to confirm that 'Adobe Sign for Salesforce Security Update' has been complete

We received an email stating 'You must update your Salesforce Org and the access token by February 3 2020*'.

I have followed all the steps given in Release notes.

After that, Is there any way to check if it's succefully got updated and no further action needed?

Steps to apply the patch as per Release notes:

In your Production environment:
1.Once the solution is vetted in your sandbox, you can install the package into your production environment by selecting the Production link from the below table
2.Revoke the access tokens in your production account, and relink the integration •The access tokens can be revoked by an Adobe Sign account admin if the SFDC admin is a different person

3.Apply any outstanding Salesforce critical updates to your production org
4.Test the production environment to verify functionality
