[Adobe Sign] What is tsid and where can I get it?

Hello, is there anyone who can advise what tsid is and where I can get it?

I am hoping that I can generate a hyperlink that navigates to each agreement using the tsid to give everyone on my organization the access to all agreements.

It seems the only way to access the document that is partially signed while it is still in progress is to sign in to Adobe. But only the people associated with that agreement (as reviewer/signer/approver, etc.) can have access to it and they have to be an Adobe user. I need everyone on my organization to have access to all agreements even while the documents are still being signed without having to sign in Adobe.

For example, on the email you receive from echosign@echosign.com once a document is fully signed, it has this 'Open agreement' button in the email and if you hover over it it gives you this address (please see below, in red). I am thinking if I could grab tsid somewhere (hopefully in bulk) I could try generate this address myself.

Any help will be appreciated. Thank you!
