Setup Liquibase to manage AWS RDS with Lambda and S3?

Brand new Liquibase user here. My team is looking to implement Liquibase to manage a new AWS Aurora RDS. We are looking to store and manage changelog files in a git repo and run a pipeline when updating the changelog to copy the repo files to S3, launch a lambda function that will then deploy the changes to the RDS.

We are comfortable with the git repo and copying files to S3 bucket, and having the lambda access and run scripts stored in S3. We typically write our lambda functions in Python. The point where we need help is understanding the best way to launch liquibase with the lambda function to run the updates to our AWS RDS.

Has anyone done something like this before and had success? Is there a better way to go about this? Any insights and/or help to accomplish this is appreciated!
