Hi @ReddyIshanvi,
It is not possible from GUI, however it can be done from crx. Please follow the steps:
- Create your custom tab (in my case it has test set as title)
- Change order of nodes, set node that represents your tab as a first one -before node that is representing Basic tab.
There is also listOrder property, but it looks value from this is not taken into consideration in terms of tabs order.
I have tested this on following AEM as a Cloud SDK version 2022.4.7138.20220427T075748Z
