 ### Checking Access Tokens
 
 - **`token_check`**: Checks for whether a token for the supplied API can be found for your current R session. For example, Qualtrics allows direct acquisition of data from R *if* you have a token and your R session "knows" that string. This function quickly checks whether you'd be able to use that workflow (currently only supports search for Qualtrics and GitHub tokens but could be easily expanded!)

+- **`issue_extract`**: Exports specified GitHub issues as PDF files when given the URL of a GitHub repository and a numeric vector of GitHub issue numbers. This function will export the first 10 issues as a default.
