Just for notes, I will leave some known issues that are not implemented yet and would be good to fix within the future PRs related to the current feature
SSUE 1. The text is not shown as styled if a user is typing it within styling frames

Steps to reproduce:

1. Open 1-1 chat with any existing contact
2. Start typing the following: **test

Actual result:
Text is not shown in the style

Expected result:
The text is shown in style during the user typing it in the style frames

ISSUE 2. Text is not shown in style if the current text is wrapped into all together styles

Steps to reproduce:

1. Open 1-1 chat with any existing contact
2. Type any text
3. Select current text and wrap it into a Bold style
4. Select current text one more time and wrap it in Italic style
5. Select current text one more time and wrap it in Strikethrough style

Actual result:
Text is not shown as styled for all selected styles
