It seems good, but before you merge:

1. Have a look on my late comments from last PR.
2. DSP-1284 doesn't exists.
3. Don't put space between PR title type and scope feat(): instead of feat ():.
4. Creating branch start with wip/ prefix, so wip/dsp-xxx instead of just dsp-xxx.

1. Have a look on my late comments from last PR.

I have updated this PR for your comments from another PR.

2. DSP-1284 doesn't exists.

Thanks, I have corrected it in PR title and description.

3. Don't put space between PR title type and scope feat(): instead of feat ():.

Done.

4. Creating branch start with wip/ prefix, so wip/dsp-xxx instead of just dsp-xxx.

Normally when I create PR they are no longer work in progress (wip). Hence I do not add wip/ in branch name.
If I still have to use the prefix wip/ for branch name even if it is ready for review, let me know and I will do it from next time. For this one, I will keep it as it is.

This what we have in our contribution guideline and I found it useful while working with git on terminal :).
