Create a consistent UX for adding content

Is your feature request related to a problem? Please describe.

• Please work with @Ayush0Chaudhary for comments, advice and review of your PR.

There isn't a consistent way of adding content. Each of these features uses a different methodology and in some cases multiple add buttons are visible.

1. Add post
2. Add event
3. Add chat (The icon is not available in current develop or main branches as chat does not work. We do not want this icon restored in this issue as it is a potential GSoC 2024 project idea. This information is just to provide some context)

This is visible here

Describe the solution you'd like

• A consistent way of adding content so that only one add icon is visible when an activity is selected.

Describe alternatives you've considered

• The LinkedIn mobile app has one possible approach (there may be others) where a right hand drawer is created that covers the previous screen when a message needs to be sent. The add post icon gets replaced with an add message icon
• There may be other apps that have other ways of achieving this goal.

Approach to be followed (optional)

• N/A

Additional context

• You must get the test code coverage up to 100% for any edited files.

@palisadoes I would like to work on this

[Ayush0Chaudhary]

Our policy is to assign no more than two issues to each contributor. This way everyone gets a chance to participate in the projects. We sometimes give exceptions for more urgent cases and sometimes we lose track, but the policy stands. You have reached your limit, please wait until your existing issues are closed before requesting more issues. You could unassign yourself from one of the other issues too.

@Ayush0Chaudhary I apologize for not checking that I have been unassigned from the issue and created a pull request for the issue. I would appreciate it if you could review this PR. It has been a week, and it's currently pending review.
