As far as my own understanding and perspective of walking process in the afterlife or in death deliberately and has been discussed and emphasized through many different portal recordings that doing such a thing is not advisable. First walking here in our physical bodies is 'easier' for lack of a better word, based on our physical bodies make up of life itself, of life substance it is equal and one, we are able to have our minds structured and seen with more ease in the physical through the mind components, thoughts, emotions, imaginations, memories, which is something in death you don't have, you no longer have access to the physical as your body is gone.
Jack through the portal just discussed this in this series of interviews:

(this one specifically)
Also, we have an opportunity many do not and by essentially giving it up and going into death believing it is going to be better is dishonest based on life existing here in life, on this earth, not in death. There is also self responsibility within all that we do, so in essence accepting and allowing this belief that it'll be better to walk process in afterlife, is not in fact real as we do not know what it'll be like in afterlife. What we do have is this moment, this life, this physical body, and this process here in this time to do our best and make the best of it. Anything else is self interest and will be not living the highest potential that can be lived, this is always the point that i cross-reference with myself, such as questions like these, 'is what i am going to do gong to create my highest potential, is it best, am i being self honest' and using self forgiveness to get through the points that are not aligned to these questions. What happens to me at death is what will happen, i am not focused on that cause it is not here, i focus on what is here and that is my breath, my application, my change, and my continued movement forward in the best i can be, this i can trust and work with each moment i am here.
As i go i will place more interviews here for more context, i am drawing a blank on one's that speak of this, you can also do a search on eqafe or google. The death research interviews are a cool glimpse into the death process and what has been experienced through beings who actually have walked this death process.
