[DIS2022_wg1] Request for talk acceptance letter

Dear Nestor, One of the authors of a talk we have accepted has just asked us to provide an acceptance letter for their talk clearly stating that they (Aurore Courtoy) will give a talk so that they can provide it to their institution to demonstrate their need to attend the conference (in person). Do you have anything we can provide for this or should we just write a more formal email from ourselves as conveners to this effect? Thanks again, Tom (for WG1 conveners)
