Regex for finding URL match if nothing and after the URL but ignore if found in multiline

Guys I need to create a regex of a URL https://www.test.com/88f19 (last 5 digits can change) and I came up with https:\/\/www.test.com\/[a-fA-F0-9]{5} and it works fine. But the problem is that I only need to match this URL if and only if nothing exists before and after this URL. e.g. this should match https://regex101.com/r/LdfVFW/1 whereas this should not match since there is some other text in multi line with the URL https://regex101.com/r/namAOd/1. Would appreciate some inputs!

>Solution :

Use \A (start of all input) and \Z (end of all input) at either end:

\Ahttps:\/\/www.test.com\/[a-fA-F0-9]{5}\Z
