Button to create calendar event based on time selection

[Tommy_Euthyphro]

Hello,

I'm fairly new to the power platform and I'd really appreciate a bit of help with creating an app - I'd like to create something to help my team let my manager know what days they will be in the office (I know there is functionality in Outlook coming, but I want to make it easier).

Essentially, I'd like a date selection at the top, with the 5 working days below, where we can click a button to create an all day calendar event in our personal calendar for the chosen day, stating 'In Office': 

So my team would just choose the week beginning date, click the days they are in the office, the click save to create the calendar events. 

I managed to get something 'working' (but not as well as I wanted) using a SharePoint list and power automate but I understand it should be possible to do something like this directly in Power Apps? Any help would be warmly received! 

Thanks in advance, 

Tom
