Hi Dip.Sarkar,
You have very limited access when using a Dynamic trail.
You will need to purchase a admin license and a extra user license.
Your cost will be around 190 a month with the extra user.
I have my own Dynamic instance. I only have 1 user and that's myself.
You can turn the extra user on and off as needed but you will be charge when the user is active.
I hope this was helpful.
