How to shorten Google cloud storage URL or can we use a custom domain?

I utilize Google Cloud Storage to host my images and PDFs. However, the challenge arises due to the lengthy URLs generated by Google Storage, making it impractical to share through text messages. Is there a solution to shorten these URLs or to employ a custom domain name, replacing the default "https://storage.googleapis.com"?

I am using Django for backend.

Sample Url - https://storage.googleapis.com/mob-uat-server/products/images/Polycab/Polycab%20Elanza%20NEO%20Storage%20Water%20Heater%2C%2015%20L%20%28POL-ElanzaNeo-15%29/129LEG115.jpeg?X-Goog-Algorithm=GOOG4-RSA-SHA256&X-Goog-Credential=mobdemandfrontend%40appspot.gserviceaccount.com%2F20240115%2Fauto%2Fstorage%2Fgoog4_request&X-Goog-Date=20240115T075737Z&X-Goog-Expires=86400&X-Goog-SignedHeaders=host&X-Goog-Signature=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
