How to correctly write .htaccess rules in order to change the URL?

Question

htaccess

Good day, Dear!
There was some problem. You need to change the URL of the admin panel.
It is necessary that when requesting to: domain.com/admin, the files should be opened from: domain.com/webasyst but without a readerect. That is, so that it remains in the address bar of the browser: domain.com/admin
Tell me , please.
Thanks in advance!

Answer 1

Something like that:
RewriteRule /admin/(.*) /webasyst/$1 [L]

Answer 2

Try:
RewriteRule /webasyst/(.*) /admin/$1 [L]
