I would advice to start with some foundational courses on NowLearning, to understand the platform and how it can be used.

Who is giving you this task and what is your experience? Because there are OOB examples of this in any clean instance. 

What do you mean with 'I should send an email within my pdi form the inbox'? You never SEND emails from the INbox. That's for incoming email. I don't know why you are tasked doing this, but please get the basic knowledge of the platform first.

Hello hello @ShariqhM,

there's been a similar question last week - it's not recommended to Close an Incident by email. Not sure if your or somebody else's...

Before you start developing, slow down and spend some design thinking. However The INC lifecycle is New - Open - In Progress - Resolved - Closed (eventually Cancelled at any stage). 

So, you should only Close the Resolved incidents, it can cause troubles to closing any other states.

Please review the ITIL best practices and ServiceNow state transitions...

You can go to a PDI, find any Incident for example on hold or in progress and try to close it - you:

Left side Resolved incident - Close button is available,
Right side In progress incident - Close button is NOT available:

The thing is that when you Resolve an incident, the Resolution information is mandatory (Res Code and Res Notes), so from Resolved to Closed, these details are already populated, to Close it from any other state it would require populating these two fields additionally and it's overall not a good practice because Resolved incident can be Reopened (see the left part of my screenshot above) while Closed one cannot be reopened nor commented.
