Capture the text using regex-CodePudding

I have a text where I need to capture the second group

Response on your Property Listing 
Dear Rahul Bond, 
A user is interested in your Property, ID 62455995: 2 BHK , Multistorey 
Apartment in Raheja Vihar , Mumbai. 
Details of Contact Made: 
Sender's Name: Test (Individual)

The text to be retrieved is 2 BHK , Multistorey Apartment in Raheja Vihar , Mumbai. This does start with **A user is interested in your Property, ID xxxxxxx: **

A user is interested in your Property, ID 62455995: 2 BHK , Multistorey 
    Apartment in Raheja Vihar , Mumbai.

The expected output is 2 BHK , Multistorey Apartment in Raheja Vihar , Mumbai.

I have tried with .match(/(A user is interested in your Property, ID.*[^:]) (.*\n.*)/g) Unfortunetly it gives me all 2 lined text.

You can use this regex:

const text = `Response on your Property Listing 
Dear Rahul Bond, 
A user is interested in your Property, ID 62455995: 2 BHK , Multistorey 
Apartment in Raheja Vihar , Mumbai. 
Details of Contact Made: 
Sender's Name: Test (Individual)`;
const rgx = /(?<=A user is interested in your Property, ID \d : )(.*\n.*)/g;

const result = text.match(rgx);
console.log(result);

From the above comment ...

"How about more generically looking for ... ID, followed by a whitespace (sequence), followed by a sequence of 8 digits, followed by a single colon, followed by another whitespace (sequence) and then capturing anything which is not a dot/period including the first occurring dot/period ... /ID\s \d{8}\:\s (?<description>[^.] \.)/g"

... and making use of the proposed regex ...

const multilineText =
`Response on your Property Listing

// see ... [https://regex101.com/r/uDFHaV/1]
const regX = /ID\s \d{8}\:\s (?<description>[^.] \.)/g;

// either ...
console.log(
  [...multilineText.matchAll(regX)]
    .map(({ groups: { description } }) => description)
);

// or ...
console.log(
  [...multilineText.matchAll(regX)]
  [0]?.groups.description
);

// ... or ...
console.log(
  regX
    .exec(multilineText)
    ?.groups.description
);
