Citroen C-Elysee 2019 rear stop lights fuse number

[jura431]

Hello everyone,
A few weeks ago my left rear stop light of my Citroen C-Elysee 2019 stopped working and I have been trying to find the fuse number for it in the fuse box and the schemes in the manual. So far I have not found anything and I was wondering if anyone knows the fuse designation so I can replace it. Thanks in advance.
P.S. (I have already downloaded the manual from this forum and while it was helpful it did not say anything about the rear light fuse or its number)

Very rare to be a fuse - try another bulb first, then check the earth to the cluster - especially the pin and the connector. Check to make sure there isn't any signs of burning or melting near in the lamp cluster connector plug that the pins connect to.
