Discord API and add a member to a chanel

I’m creating a scenario for onboarding my customers on discord, and at one point I need to create a private channel for me and the customer (you can see it circled in red in the photo below), but I don’t know how, after creating the channel, to add the user to it.

Do you know how I can add the member directly after creating the private channel, please?

PS: If you have any ideas on how to optimise the workflow, please don’t hesitate to contact me :wink:

Thanks in advance,
Enzo

Were you able to figure this out?

I’m trying to do the same, setup a private channel and then add a user to with their Discord ID.

I tried using the overwrite permissions on the channel creation but it doesn’t seem to like using a User ID number, maybe just Roles?
