As per the error message below error you can see your user have write permission
but you are trying to perform the join/action
on resource group level subscriptions/subscriptionName/resourceGroups/
The client has permission to perform action 'Microsoft.Logic/workflows/write' on scope '/subscriptions/subscriptionName/resourceGroups/resourceGroupsName/providers/Microsoft.Logic/workflows/LogicAppName'; however, it does not have permission to perform action 'join/action' on the linked scope(s) '/subscriptions/subscriptionName/resourceGroups/' or the linked scope(s) are invalid.
In case if someone has specified the logic app contributor permission or any of the build in role access then please verify if that RBAC role have the required permission or not.
In the above case if someone has specified the logic app contributor permission at the resource group level then the user would not have the join/action permission on the subscription resource group.
You need to either specify the subscription level contributor or subscription level logic app contributor permission.
