@Nidhi Priya, Thanks for posting in Q&A.
To deploy app via Intune, for example win32 app, the app needs to have install command which can run silently without user interaction. Then we will consider deploy via Intune win32:
https://learn.microsoft.com/en-us/mem/intune/apps/apps-win32-add#step-2-program
For the ShareA app, please contact the app developer to confirm if the app can be installed silently without user interact and get the install command.
After we get the command, try to test on one device manually to see if it can be installed successfully under system account. To run application under system account, you can use PsExec tool.

Here is a link with more details for your reference:

Note: Non-Microsoft account, feel free to let us know.
If the app is failed to be installed when we test manually on the device, you need to contact the app developer to fix the issue. After the above test is successful, we can consider deploy it via Intune win32 to see if it can work.
Hope the above information can help.
