This will be needed for the 8.6.1 patch, will need to be updated once the 8.6 versioned docs are live, do not merge yet.

I don't have any context for this change. When will the 8.6.1 patch go out?

[nicpuppa]

Not sure if this need to be available in 8.6 and 8.6

[akeller]

The file modified in this PR is for /next or the preview for 8.7.

[megglos]

in the meantime 8.6 was covered with #4473, only 8.5 is open to be included once the next 8.5 patch is released.

@megglos @nicpuppa, I'm admittedly a bit confused about the status of this PR. Do we need to merge this change for 8.7 (current scope of the PR)? Or just 8.5? If it's just for 8.5, we need to adjust this PR.

@megglos @nicpuppa Checking in. Could you please provide a status update for this PR so I can assist if necessary?

[nicpuppa]

@christinaausley I think this property needs to be added in the 8.5 docs, but I'm honestly not sure about it

[megglos]

It's not to be included in 8.5 as it wasn't backported in the end (as config implementation changed significantly).

As sdk config changed from 8.5 to 8.6 anyway I would suggest we just add the usage of the ZEEBE_TOKEN_SCOPE env var for the scope to the already listed env vars for 8.5 .
