user space permission remove

[soumyajit]

I want to remove  particular user permission from multiple spaces using confluence API through script runner console. Could you please help me with this matter?

def spacePermissions
def spaces = spaceManager.getAllSpaces()
def permissionsToRemove = []

spaces.each{ space ->
if(space.getKey()=='CSCO'){
spacePermissions = space.getPermissions()
spacePermissions.each{ it ->
if (it.getUserName() == "poc" && it.getType() == "VIEWSPACE"){
permissionsToRemove.add(it)
}
}
}
}

permissionsToRemove.each{it ->
log.warn it
//log.warn permissionsToRemove
//spacePermissionManager.removePermission(it)
spacePermissionManager.removePermission(it)
}

// but removePermission is invalid method
