To clarify on the answer provided by Kevin Patel you can get the link directly from your browser, however you must have the reading pane set to "No split", otherwise you get a generic URL.

You can specify the inbox email address in the link to open the email in the correct inbox.
if INBOX@EMAIL.COM is your inbox email
Create the link as follows
https://mail.google.com/mail/u/INBOX@EMAIL.COM/#all/YOUR_EMAIL_ID
Since Google introduced the integration of Google Tasks and Gmail a few weeks ago, one way you can get the URL of a specific Gmail email us:
Enjoy!
If you are happy with a bookmarklet that copies a link to the current email to your clipboard, you can try adding this to your bookmarks:
javascript:(function()%7Basync%20function%20copyPermalink()%20%7Btry%20%7BsearchURL%20%3D%20'https%3A%2F%2Fmail.google.com%2Fmail%2Fu%2F0%2F%23search%2Fmsgid%253A'%3BmessageId%20%3D%20document.querySelector('div%5Bdata-message-id%5D').getAttribute('data-message-id').substring(7)%3Bawait%20navigator.clipboard.writeText(searchURL%20%2B%20messageId)%3Bconsole.log('Mail%20message%20permalink%20copied%20to%20clipboard')%3B%7D%20catch%20(err)%20%7Bconsole.error('Failed%20to%20copy%3A%20'%2C%20err)%3B%7D%7DcopyPermalink()%7D)()
It essentially searches the currently focussed email for its data-message-id attribute, and then converts that into a search url using the msgid predicate (this doesn't seem to be documented, but was quite guessable.). The full link is then copied to your clipboard.
Caveat: Seems to work with or without a preview pane, but this hasn't been extensively tested.
