@julian thank you so much i was using the wrong key groupTitle instead of groups

first sorry for my english it is not my first language

i am using the session sharing plugin and it is working wonderful , the users on my app login directly to the nodeBB, but i need to classify them into groups I created two group already from the admin panel (Group-1 , Group-2) as i under stand i need to setup the settings from the admin panel and put the group title at the JWT payload that i send to be saved at the cookies

here is how my payload looks like id: uuid,
email: [email protected],
username: username,
groupTitle: 'Group-1',

but when i check the user on nodebb i notes that the user created and logged in successfully but the user join no group ... is it the right approach ??? what to do??
