Please add the ability to also share text.

**Is your feature request related to a problem? Please describe.**
No

**Describe the solution you'd like**
Just a feature request - Please add the ability to share not only files etc but also to share just 'text' like we see in a similar app called **Sharik** (https://github.com/marchellodev/sharik)

Additional context
If this feature is added - this will surely make **ShareX** the **all-in-one** sharing solution for android.


No file or test is named. Start by tracing the existing Android file-sharing flow and compare its entry points with the text-sharing behavior shown in the Sharik reference. Done means users can share plain text as well as files.
