Description

We will collate a list of usernames for the survey we are looking to put out.

Our software allows us to generate a unique URL token for every invitation we put out. By doing this, we:

1. Will be able to segment the population of users in our analysis
2. Won't need a captcha!

We want to send a direct message to users we sample with a unique URL for each - and for that direct message to be localised.

Acceptance criteria

Given a table (or key-value pair) of usernames + unique URLs:

1. The /@/Lichess account must send a single direct message to all usernames
2. The direct message must accept a URL value from the table, which matches the recipient's username
3. The message must be sent in the user's language of choice, defaulting back to English if no translation is available
