I propose to add Clément to the astropy security team.
See https://www.astropy.org/team for a list of current roles. Following APE 0 [1] we leave a two week long comment period for this proposal where you can comment publicly on the PR [2] or privately to the CoCo (coordi...@astropy.org or DM one of them on Slack). If there are no objections after two weeks, the CoCo shall merge the PR.
Yours,
Moritz
