There are two ways to do this:
1) User reports

Go to Google Analytics> Audience> User Explorer. Create a custom segment for your form of interest (in terms of event data), for example. Prerequisites> Filter sessions for inclusion> Event Category Contains Forms> Event Action Contains My Interest Form
The resulting window will show you each client identifier, the number of sessions of each client, the duration of the session, etc., as well as the conversion rate of the target. Please note that this is a general goal conversion rate and is not specific to a specific goal.
You can then examine client behavior during and within sessions, and have a list of specific interactions that have been captured in Google Analytics.
2) Custom reports
The second option is to export all the behavior using custom dimensions Client, Session and Timestamp. To do this, you need to create your own report for three custom dimensions along with Page Path.
After you exported the page path data, you will need to repeat the events (since they must be requested separately).
After you export the data, you can join your data sets and get the full csv output of each of your sessions. This gives you the ability to view the process data of any session containing the interaction of interest.
This method is more complex, but ultimately provides you with more flexibility.
Limitations:. This will be limited to data sent to GA. I. If the links are not being tracked, you will not be able to identify each link that the user clicked.
--- Update ---
If you want to understand the flow of a specific user specific to an email or manual request, you will also need to capture a unique identifier. For example, you might have a hidden field with a random number. This randomly generated number will be sent along with the email. In addition, this randomly generated number must be captured by the email request event, which allows you to identify specific email requests in compliance with the PII GA conditions.
