Of course run an automated test suite runs faster then manual testing. But it'll take an incredible amount of resource (time and developers) to write the automation script. So, write it against stable parts of your software. Usually regression test suites.
If not, you'll spend a huge time and developers to write scripts to something keeps changing.
Not to mention that a lot of the automation tools, even Selenium, Pupetter and Playwrite, they'll fail a lot (i.e., false negatives). To the point that sometimes you have to disable the CI when you have a lot of developers submitting pull requests.
