is exactly what it sounds like. There is a twitter thread and script here. You can figure out who your senator is and how to contact them at senate.gov.
If you cannot call and want me to call for you, please send me a message with your full name, zip code, and, optionally, your street address and/or phone number and/or email address. You can do this on anon or not.
Even if your Senator supports the bill, you can call them and thank them.
Also, follow Celeste Pewter on twitter.
