Selecting text of a message

### Your use case

#### What would you like to do?

I would like to be able to only select a portion of a text message. Currently the only way I found is to copy the whole message, paste it somewhere and then select what I really need.

#### Why would you like to do it?

Because sometimes things like an email address is sent which I want to copy for example to create a new contact.

#### How would you like to achieve it?

Maybe a special mode in which the message becomes a text where all the OS default text tools are available

### Have you considered any alternatives?

### Additional context

No file or test is named. Start by reproducing the current whole-message copy behavior in the iOS message view and inspect how message interaction is implemented. Done means a user can select only part of a message and use the standard iOS text actions, including copying the selected portion.
